Lloyd Eugene Schlup, a Missouri death row inmate, appeals from the judgment of the district court1 denying his petition for a writ of habeas corpus under 28 U.S.C. § 2254 (1988). Schlup asserts that the district court erred in holding that many of his ineffective assistance of counsel claims were procedurally barred, in denying another ineffective assistance of counsel claim on the merits, and in failing to grant him an evidentiary hearing on his habeas petition. Additionally, on the eve of oral argument before this court, Schlup filed a motion requesting this court to hold in abeyance a ruling on the merits of this appeal and allow him to submit certain claims to the Missouri state courts.2 We deny the motion and affirm the judgment of the district court.
I. BACKGROUND
On December 11,1985, while in prison on an unrelated matter,3 Schlup was convicted of capital murder in the death of a fellow inmate.4 Schlup’s conviction and sentence *635were affirmed on direct appeal by the Missouri Supreme Court. State v. Schlup, 724 S.W.2d 236 (Mo.), cert. denied, 482 U.S. 920, 107 S.Ct. 3198, 96 L.Ed.2d 685 (1987).
Schlup filed a state court motion for post-conviction relief under Missouri Supreme Court Rule 27.26. Schlup argued that his sentence and conviction should be vacated because he was denied effective assistance of trial counsel. Schlup claimed that his trial counsel failed to prepare for aggravating circumstances testimony and request a continuance of the trial to prepare for the testimony, and to investigate and call additional alibi witnesses. After an evidentiary hearing, the Missouri court held that Schlup’s trial counsel was not ineffective and denied Schlup’s claim for post-conviction relief.
Schlup appealed the denial of post-conviction relief to the Missouri Supreme Court. Schlup reasserted the ineffectiveness claim based on aggravating circumstances testimony, but he did not reassert the argument that trial counsel failed to investigate and call additional alibi witnesses. The Missouri Supreme Court affirmed the denial of post-conviction relief on direct appeal. Schlup v. State, 758 S.W.2d 715 (Mo.1988).
Schlup subsequently filed a petition for writ of habeas corpus in federal district court asserting numerous claims based on ineffective assistance of counsel. Schlup reasserted the claim that his trial counsel was ineffective in failing to prepare for aggravating circumstances testimony or request a continuance, and the claim that trial counsel was ineffective in not calling additional alibi witnesses. In addition, Schlup asserted, for the first time before the district court, claims based on trial counsel’s failure to offer psychiatric or psychological testimony as mitigating evidence during the guilt phase of Schlup’s trial, and failure to object to unconstitutional jury instructions. Schlup argued that none of his claims should be proeedurally barred because the ineffective assistance of his state court appellate and post-conviction counsel provided cause to justify the procedural default, and that prejudice resulted from the ineffective assistance. Schlup requested, but was denied, an evidentiary hearing on his petition.
The district court denied Schlup’s petition. The court held that Schlup’s new claims, that trial counsel was ineffective in failing to offer psychiatric or psychological testimony and to object to jury instructions, as well as the previous claim that trial counsel failed to call additional alibi witnesses, were proeedurally barred. The court concluded that these claims had not been adequately raised or pursued in state court and that Schlup failed to demonstrate cause for the procedural default.5 Schlup’s remaining claim, that trial counsel failed to prepare for aggravating circumstances testimony and request a continuance of the trial, had been, according to the district court, exhausted in state court. However, the claim was denied on its merits.
On appeal to this court, Schlup raises all of the same claims for ineffective assistance of counsel stated above. In addition, Schlup raises an additional claim not raised in either the state courts or the federal district court. He states that trial counsel failed to object to the state’s prejudicial closing argument.6 Thus, in sum, *636Schlup asserts four claims which have not been addressed by the state courts. They include his trial counsel’s failure to call additional alibi witnesses, offer psychiatric or psychological testimony as mitigating evidence, object to unconstitutional jury instructions, and object to the state’s prejudicial closing argument. He also asserts one exhausted claim based on his trial counsel’s failure to be prepared to present aggravating circumstances testimony at trial. Schlup argues that all of his ineffectiveness claims should be granted on their merits because the ineffective assistance of his appellate and postconviction counsel provides cause to justify any procedural default. In addition, Schlup asserts that the district court erred in not granting him an evidentiary hearing on his habeas corpus petition.
II. DISCUSSION
A. Motion to Hold Appeal in Abeyance
One day before oral argument Schlup filed a motion to hold this case in abeyance. Schlup requests this court to postpone a ruling on the merits of this appeal and allow him to submit certain habeas claims to the Missouri state courts. We deny the motion.
In his motion, Schlup asserts that a recent decision of the United States Supreme Court establishes that he is entitled to relief on his habeas petition, and he argues that this claim should be presented to the state courts before proceeding with this appeal. Schlup contends that Mills v. Maryland, 486 U.S. 367, 108 S.Ct. 1860, 100 L.Ed.2d 384 (1988), which was decided after Schlup’s trial and commencement of post-conviction proceedings, establishes that a jury instruction given in Schlup’s trial was unconstitutional. In Mills, the state sen-fencing scheme required the imposition of the death penalty if mitigating circumstances did not outweigh aggravating circumstances. The jury instruction at issue in Mills required the jury to unanimously find the existence of the same mitigating circumstance before such circumstance could be considered by the jury to outweigh any aggravating circumstances. The Supreme Court invalidated the instruction because the instruction prevented individual jurors from considering all relevant mitigating circumstances, whether unanimously perceived or not, as a basis for imposing a penalty less than death. Id. at 384, 108 S.Ct. at 1870.
Schlup asserts that a jury instruction given in his case similarly required the jury to unanimously find the same mitigating circumstance before the jury could consider whether that mitigating circumstance outweighed any aggravating circumstances. See Respondent’s Exhibit B at 98 (jury instruction 19). Thus, Schlup argues that the jury at his trial was required to impose the death sentence if it could not unanimously find the same mitigating circumstance. Schlup asserts that holding this appeal in abeyance pending further state action is an appropriate remedy. See Fletcher v. Armontrout, 733 F.Supp. 1348, 1349 (W.D.Mo.1990) (court held habeas petition in abeyance pending state action). See also Byrd v. Delo, 917 F.2d 1037, 1039 (8th Cir.1990) (court may reconsider habeas claims if petitioner has shown a change in the law).
This appeal should not be held in abeyance. Schlup seeks to return to state court and present a claim under the provisions of Missouri Supreme Court Rule 91, rather than the post-conviction relief provisions of Rules 24.035 and 29.15.7 The Mis*637souri Supreme Court has not determined whether a petitioner may bring a Rule 91 petition after other post-conviction proceedings, or whether Rule 29.15 provides the exclusive post-conviction remedy to incarcerated persons. Because federal courts may not grant a habeas corpus petition unless the petitioner has exhausted all state remedies, see 28 U.S.C. § 2254(b), this undecided question has created problems in resolving exhaustion issues in federal habeas actions. See Hampton v. Miller, 927 F.2d 429 (8th Cir.1991); Fletcher, 733 F.Supp. at 1349. Although given the opportunity, the Missouri Supreme Court has chosen not to clarify the status of Rule 91. See Fletcher, 733 F.Supp. at 1349 (discussing the Missouri Supreme Court’s failure to address this question when certified); White v. State, 779 S.W.2d 571, 573 (Mo. 1989) (noting that the writ of habeas corpus arises from the Missouri Constitution and “may not be eliminated by statute or rule,” but declining to resolve whether a remedy is available under Rule 91). We do not have to reach this issue, however, because even if a remedy is available to Schlup in state court, permitting Schlup to return to state court would be futile. See Powell v. Wyrick, 657 F.2d 222, 224 (8th Cir.1981) (exhaustion requirement excused as futile if state court will not hear petitioner’s claim).
The Missouri Supreme Court has previously rejected the Mills argument now advanced by Schlup. See State v. Petary, 790 S.W.2d 243, 245 (Mo.), cert. denied, — U.S. -, 111 S.Ct. 443, 112 L.Ed.2d 426 (1990); State v. Smith, 781 S.W.2d 761, 768 (Mo.1989), vacated and remanded, — U.S.-, 110 S.Ct. 1944, 109 L.Ed.2d 306, aff'd on remand, 790 S.W.2d 241 (1990). In Petary and Smith, the Missouri Supreme Court rejected the Mills argument on two bases. First, the court held that the mitigating circumstance instruction given in Missouri, which is a form instruction traditionally used by Missouri courts, is “markedly different” than the instruction given in Mills, and that the language of the Missouri instruction does not require a jury to be unanimous in finding each mitigating circumstance. Smith, 781 S.W.2d at 768. Second, the court held that Mills is not applicable to the Missouri instructions because an additional instruction used by Missouri courts specifically gives the jury discretion to impose a life sentence rather than death despite the existence of any aggravating circumstances. Petary, 790 S.W.2d at 246; Smith, 781 S.W.2d at 768. See also Roberts v. State, 775 S.W.2d 92, 96 (Mo.) (Blackmar, C.J., concurring) (distinguishing Mills), cert. denied, — U.S. -, 110 S.Ct. 1506, 108 L.Ed.2d 640 (1990).
The mitigating circumstance instruction given in Petary and Smith contained the same relevant language as the instruction given in Schlup’s trial. Compare Respondent’s Exhibit B at 98 (jury instruction 19) (“If you unanimously decide that a sufficient mitigating circumstance or circumstances exist which outweigh the aggravating circumstance or circumstances found by you to exist, then you must return a verdict fixing defendant’s punishment at imprisonment for life....”) with Petary, 790 S.W.2d at 244-45 (“If you unanimously find that one or more mitigating circumstances exist sufficient to outweigh the aggravating circumstances found by you to exist, then you must return a verdict fixing defendant’s punishment at imprisonment for life_”) and Smith, 781 S.W.2d at 767-68 (same language as Petary). In addition, the Missouri instruction giving the jury discretion to impose a life sentence rather than death despite the existence of any aggravating circumstances was given in Schlup’s trial. Compare Respondent’s Exhibit B at 99 (jury instruction 20) with Petary, 790 S.W.2d at 246 and Smith, 781 S.W.2d at 768.
B. Merits of Appeal
On review of an application for ha-beas corpus, the issue of effective assistance of counsel presents a mixed question of law and fact. Thus, this court may review the district court’s conclusions on ineffectiveness de novo. Laws v. Ar-*638montrout, 863 F.2d 1377, 1381 (8th Cir.1988) (en banc), cert. denied, 490 U.S. 1040, 109 S.Ct. 1944, 104 L.Ed.2d 415 (1989). The district court’s findings of fact, however, are reviewable under the clearly erroneous standard. Id. We conclude that the district court did not err in barring claims not raised in state court, or in denying Schlup’s remaining claim on its merits. Furthermore, the district court was not required to hold an evidentiary hearing on Schlup’s petition.
1. Ineffective Assistance of Counsel
To prevail on a claim of ineffective assistance of counsel, Schlup must satisfy the two-step test announced in Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 2064, 80 L.Ed.2d 674 (1984). First, Schlup must establish that counsel provided professionally unreasonable service. Counsel’s errors must be so egregious that counsel was not functioning as the “counsel” guaranteed by the Sixth Amendment. Second, Schlup must demonstrate that counsel’s inferior performance prejudiced the defense to the extent that he was denied the right to a fair trial. There must be a reasonable probability that but for counsel’s errors, the result of the trial would have been different. Upon reviewing a claim based on ineffective assistance of counsel, the court presumes that counsel’s performance “falls within the wide range of reasonable professional assistance.” Id. at 689, 104 S.Ct. at 2065. The court need not consider the prejudice element if the performance element has not been satisfied, and vice versa. Id. at 697, 104 S.Ct. at 2069-70.
a. Claims Not Properly Raised in State Proceedings
Schlup’s claims based on trial counsel’s failure to call additional alibi witnesses, offer psychiatric or psychological testimony, object to unconstitutional jury instructions, and object to the state’s prejudicial closing argument have not been properly presented to the state courts. Ordinarily, claims not properly presented to state courts will be barred from consideration by a federal court on habeas review unless the appellant can demonstrate cause for the procedural default and actual prejudice. Wainwright v. Sykes, 433 U.S. 72, 90, 97 S.Ct. 2497, 2508, 53 L.Ed.2d 594 (1977). Schlup asserts that the ineffective assistance of his state court appellate counsel and post-conviction counsel provides cause to justify the procedural default, and that prejudice will result from barring the claims. Schlup claims that appellate counsel did not raise trial counsel’s errors on the appeal of Schlup’s conviction, and that post-conviction counsel similarly failed to raise these claims in the post-conviction proceeding.
The district court barred the claims which had not been properly raised in state court, reasoning that ineffective assistance of post-conviction counsel could not constitute the cause necessary to excuse the procedural default. The court held that the cause required to excuse a procedural default must be cause that could constitute an independent ground justifying habeas corpus relief, and ineffectiveness of post-conviction counsel is not an independent basis for such relief. See Schlup v. Armontrout, No. 89-0020C(3), slip op. at 11 (E.D.Mo. May 31, 1989) (citing Murray v. Carrier, 477 U.S. 478, 489, 106 S.Ct. 2639, 2646, 91 L.Ed.2d 397 (1986); Mitchell v. Wyrick, 121 F.2d 773, 774 (8th Cir.), cert. denied, 469 U.S. 823, 105 S.Ct. 100, 83 L.Ed.2d 45 (1984)).8
*639The posture of this appeal dictates that we address the merits of the four underlying claims of ineffective assistance of trial counsel, rather than the procedural bar issue. The district court did not determine whether appellate counsel or post-conviction counsel were ineffective, and there is insufficient evidence in the record to evaluate these issues. The record, however, contains sufficient evidence to evaluate trial counsel. The actions of appellate and post-conviction counsel, given the claims asserted by Schlup, are relevant only in connection with trial counsel’s competence. This appeal, therefore, can be resolved by addressing the merits of trial counsel’s performance. See Long v. Iowa, 920 F.2d 4, 6 n. 2 (8th Cir.1990) (resolving merits of a claim because decision on merits was less complicated than procedural bar issue). Moreover, addressing the merits of Schlup’s claims will not prejudice appellee.
We find that trial counsel’s performance was not ineffective under the two-step test of Strickland. First, trial counsel was not ineffective under the performance component of Strickland in not investigating and calling additional alibi witnesses at the guilt phase of Schlup’s trial. Schlup’s principal argument during trial was that he was innocent of the murder, and he sought to establish that he was not present at the time and place of the offense. Trial counsel called three alibi witnesses, Oscar Dunbar, Bernard Bailey and Arthur St. Peter. Schlup did not advise trial counsel that additional persons, Robert O’Neal, Van Robinson, Lamont Griffin and Ricky McCoy, could also serve as alibi witnesses, and trial counsel did not interview or call any other person as an alibi witness. However, during his preparation for trial, counsel reviewed the testimony given by O’Neal at two previous trials of Schlup’s co-defendants, and he reviewed statements of Griffin and McCoy which were given to investigators after the murder. Based on his review, trial counsel concluded that O’Neal’s testimony could be damaging, and that any other testimony would be repetitive of the testimony to be presented at trial. Counsel was not ineffective in failing to interview and call witnesses whose testimony would be repetitive or potentially damaging, especially when Schlup failed to inform counsel of the possibilities of these witnesses with regard to an alibi defense.
Second, Schlup has not demonstrated that trial counsel’s failure to offer expert psychiatric or psychological testimony as mitigating evidence prejudiced his case. In light of the numerous aggravating circumstances, including convictions for assault and involvement in a murder while incarcerated, the undeveloped testimony would not have been of sufficient weight to have changed the outcome of Schlup’s trial. The expert psychiatric or psychological testimony would not with “reasonable probability” have been likely to change Schlup’s sentence. Strickland, 466 U.S. at 694, 699-700, 104 S.Ct. at 2068, 2070-71. See Stokes v. Armontrout, 851 F.2d 1085, 1095-96 (8th Cir.1988), cert. denied, 488 U.S. 1019, 109 S.Ct. 823, 102 L.Ed.2d 812 (1989). Trial counsel’s performance was within the bounds of professional competency.9
*640Third, trial counsel’s failure to object to jury instructions is not ineffective assistance under Strickland. Schlup asserts that jury instructions 17-21, which include the aggravating and mitigating circumstances instructions, were unconstitutional and trial counsel should have objected to their use. According to Schlup, the jury instructions were unconstitutional in two respects. First, the instructions were unconstitutional under Mills because they required the jury to unanimously find the same mitigating circumstance before the jury could consider whether that circumstance outweighed any aggravating circumstances. Second, the instructions were unconstitutionally vague because they did not define “aggravating circumstances” and “mitigating circumstances.” Schlup asserts that vagueness is established by the jury’s request to the court during deliberations for a definition of “aggravating circumstances,” which definition the court declined to give.
Schlup has not satisfied the two-step test in Strickland respecting the jury instructions. The constitutional argument based on Mills is the same argument Schlup asserted in his motion to hold this appeal in abeyance. As stated in our discussion of that motion, his argument lacks merit. Furthermore, Schlup has not demonstrated that the failure to object on vagueness grounds prejudiced his case. The jury determined that two aggravating circumstances existed on the facts of Schlup’s case, that Schlup had a substantial history of serious assaultive behavior and that the murder was committed by Schlup while in a place of lawful confinement. The jury found no mitigating circumstances to outweigh them. Even assuming confusion on the jury's part respecting the meaning of aggravating circumstances, the two circumstances found by the jury were in fact present in this case and were aggravating in nature. Schlup has not demonstrated how clarifying the alleged confusion would have prevented the jury from finding their presence. Thus, there is no reasonable probability that a vagueness objection by trial counsel would have changed Schlup’s sentence.
Fourth, Schlup has not established prejudice from the state’s closing argument at the penalty phase. The state declared that persons have a right to be free from fear and suggested that Schlup should be sentenced to death because he may otherwise eventually be released into society. Schlup contends that the argument was intended to inflame the passion of the jury and impair the jury’s reason, and that trial counsel should have objected to the argument and made a request for a curative instruction.
Schlup was not prejudiced by the closing argument because Schlup’s sentence was not imposed under the influence of passion. First, the Missouri Supreme Court has found “no indication that the death sentence was imposed under the influence of passion, prejudice, or any other contribu*641ting factor.” Schlup, 724 S.W.2d at 242.10 The state court’s factual findings are entitled to a presumption of correctness. 28 U.S.C. § 2254(d); Laws, 863 F.2d at 1386 & n. 9. Second, irrespective of the state court’s findings, no prejudice occurred because the state’s actions were not so egregious that the closing argument rendered Schlup’s trial fundamentally unfair. See Donnelly v. DeChristoforo, 416 U.S. 637, 647, 94 S.Ct. 1868, 1873, 40 L.Ed.2d 431 (1974) (warning against finding that every improper argument of a state prosecutor presents a constitutional violation); Hamilton v. Nix, 809 F.2d 463, 470 (8th Cir.) (petitioner must show a reasonable probability that absent the alleged improper closing statements the result would have been different), cert. denied, 483 U.S. 1023, 107 S.Ct. 3270, 97 L.Ed.2d 768 (1987).
Schlup’s claims, for the reasons stated, lack merit. Therefore, Schlup has not demonstrated that trial counsel provided ineffective assistance of counsel under the Strickland test.
b. Claim Properly Raised in State Proceedings
Schlup’s sole claim which was properly presented to the state courts is based on trial counsel’s failure to prepare for aggravating circumstances testimony and to request a continuance of the trial to prepare to meet such evidence. The district court concluded that trial counsel was not ineffective.
During the penalty phase of Schlup’s trial, several of Schlup’s prior convictions for assault were placed in evidence to establish the presence of aggravating circumstances. As a part of this evidence, the state presented live testimony of Harold Johnson, one of Schlup’s assault victims. Johnson was a former cellmate and he testified in detail about an assault and sodomy perpetrated on him by Schlup and another inmate. Schlup’s trial counsel did not realize that Johnson would be called as a witness and consequently did not prepare, pri- or to trial, for Johnson’s testimony. During the discovery stage of Schlup’s murder trial, however, the state supplied trial counsel with investigative reports concerning Johnson which had been compiled for the trial of Schlup’s assault and sodomy against Johnson. The state informed counsel at that time that the state intended to introduce the reports into evidence during the penalty phase. Trial counsel was not informed of the state’s intention to call Johnson as a live witness, however, until the conclusion of the guilt phase of Schlup’s trial, two days before the penalty phase commenced. Trial counsel strenuously objected to Johnson’s testimony, arguing that he received inadequate notice and that the testimony would be overly prejudicial, but he was overruled. The court did, however, permit trial counsel to interview Johnson for approximately forty-five minutes before the penalty phase commenced.
Trial counsel’s performance with respect to Johnson’s testimony “falls within the wide range of reasonable professional assistance” under Strickland, 466 U.S. at 689, 104 S.Ct. at 2065. Counsel was given short notice of the proposed testimony, and strenuously objected to the testimony. Upon being advised that his objection was overruled and that Johnson would testify, counsel was able to prepare an adequate response to the testimony. Counsel was able to interview Johnson for forty-five minutes before the guilt phase of the trial, and counsel possessed investigative reports concerning Johnson from which he could anticipate the substance of Johnson’s testimony. In addition, counsel carefully explored Johnson’s criminal record on cross-examination.
Furthermore, although counsel may not have formally requested a continuance on the record at trial, counsel testified at Schlup’s state post-conviction proceeding that he asked the trial court for time to depose Johnson. 27.26 Transcript at 65. Instead of permitting the deposition, the *642court, as indicated, allowed counsel time to interview Johnson. Trial counsel’s performance respecting Johnson's testimony, under the circumstances, was not constitutionally inadequate.
2. Evidentiary Hearing
Schlup asserts that the district court improperly denied his request for an evidentiary hearing on his habeas corpus petition. Schlup requested an evidentiary hearing before the district court to establish that the state court, in Schlup’s post-conviction action, committed error in denying a motion by Schlup to continue the post-conviction hearing. Schlup requested a continuance of his post-conviction proceeding to obtain additional evidence on Schlup’s claim of innocence, including photographs of the crime scene from the perspective of witnesses to the murder, presentation of additional witnesses to rebut the state’s evidence, and evidence of the time required to travel from the crime scene to the dining hall where Schlup was seen on videotape shortly after the murder. The state court denied the motion, and Schlup requested an evidentiary hearing in the district court to attempt to establish the facts that would have been presented in state court had the continuance been granted. The district court denied Schlup’s request.
The district court did not err in denying Schlup’s request for an evidentiary hearing. Habeas corpus relief is available to an incarcerated person “ ‘only on the ground that he is in custody in violation of the Constitution or laws or treaties of the United States.’ ” Mitchell v. Wyrick, 727 F.2d 773, 774 (8th Cir.), cert. denied, 469 U.S. 823, 105 S.Ct. 100, 83 L.Ed.2d 45 (1984) (quoting 28 U.S.C. § 2254(a)). Schlup’s claim that the state court should have granted his motion to continue the post-conviction hearing alleges, as an independent ground for relief on habeas review, an infirmity in the state’s post-conviction proceeding. The claim presents a challenge to a state court proceeding which is collateral to Schlup’s detention, rather than a constitutional challenge to the detention itself. Schlup’s claim, therefore, is not cognizable in a habeas corpus action, and the district court was not required to grant Schlup an evidentiary hearing on the issue.
III. CONCLUSION
Schlup was not denied effective assistance of trial counsel. Furthermore, Schlup’s claim that the district court erred in failing to grant him an evidentiary hearing is based on a claim which is not cognizable in a federal habeas corpus proceeding. The judgment of the district court denying Schlup’s petition for a writ of ha-beas corpus is affirmed.
. The Honorable William L. Hungate, United States District Judge for the Eastern District of Missouri.
. Schlup also filed an affidavit in support of the motion, which was followed by appellee’s motion to strike the affidavit and Schlup’s response to the motion to strike. The affidavit shall not be considered because it was not part of the record on appeal. See Fed.R.App.P. 10. Therefore, the motion to strike is moot.
. Schlup was convicted of committing assault and sodomy against a cellmate, Harold Johnson, while in the Pettis County Jail. See 27.26' Transcript at 59. See also State v. Schlup, 724 S.W.2d 236 (Mo.) (discussing Schlup’s conviction of assault and sodomy), cert. denied, 482 U.S. 920, 107 S.Ct. 3198, 96 L.Ed.2d 685 (1987). Johnson was later called as a witness in Schlup's murder trial. See text infra at 641-42.
.Two co-defendants, Robert O'Neal and Rodnie Stewart, were also convicted of the same murder in separate trials. See Schlup, 724 S.W.2d at 238. O'Neal was convicted of capital murder and sentenced to death. State v. O’Neal, 718 S.W.2d 498 (Mo.1986), cert. denied, 480 U.S. 926, 107 S.Ct. 1388, 94 L.Ed.2d 702 (1987). Stewart *635was convicted of capital murder and sentenced to life imprisonment without parole for fifty years. State v. Stewart, 714 S.W.2d 724 (Mo.Ct.App.1986). The facts of the murder are fully set forth in the opinion of the Missouri Supreme Court in Schlup, 724 S.W.2d at 238.
. Schlup also argued that his claims should be considered despite the procedural default because his conviction and sentence were fundamentally unfair. Schlup contended that in appropriate cases the procedural default "principles must yield to the imperative of correcting a fundamentally unjust incarceration.” Engle v. Isaac, 456 U.S. 107, 135, 102 S.Ct. 1558, 1575-76, 71 L.Ed.2d 783 (1982). See Wainwright v. Sykes, 433 U.S. 72, 91, 97 S.Ct. 2497, 2508-09, 53 L.Ed.2d 594 (1977). The district court, however, concluded that Schlup could not demonstrate such injustice.
. Schlup asserts that this claim had been presented before the district court. In his reply brief, Schlup directs opposing counsel and the court to the reply brief he filed in district court. Appellant’s Reply Brief at 2. We have not been supplied with a copy of the brief referenced by Schlup. However, we note that this claim was not raised in either Schlup’s motion for post-*636conviction relief, see 27.26 Legal file at 4, or during the post-conviction hearing, see 27.26 Transcript, and the district court did not address this claim in either of its orders. See Schlup v. Armontrout, No. 89-0020C(3), slip op. (E.D.Mo. Nov. 21, 1989); Schlup v. Armontrout, No. 89-0020C(3), slip op. (E.D.Mo. May 31, 1989). Thus, we consider the claim as raised for the first time on this appeal.
. Effective January 1, 1988, the Missouri Supreme Court adopted Rule 29.15, which together with Rule 24.035, repealed and replaced Rule 27.26. Although Schlup was sentenced before January 1, 1988, while Rule 27.26 was effective, he sought and was denied post-conviction relief under Rule 27.26, and that proceeding is no longer pending. Thus, any additional post-conviction proceeding by Schlup would not be governed by Rule 27.26, but by Rules 24.035 and *63729.15. See Rule 29.15(m); Barks v. Armontrout, 872 F.2d 237, 239 (8th Cir.1989).
. This circuit has clearly announced, after the district court’s judgment, that ineffectiveness of post-conviction counsel can excuse a procedural default. See Simmons v. Lockhart, 915 F.2d 372, 376 (8th Cir.1990); Shook v. Clarke, 894 F.2d 1496, 1497 (8th Cir.1990); Shaddy v. Clarke, 890 F.2d 1016, 1018-19 & n. 4 (8th Cir.1989); Harper v. Nix, 867 F.2d 455, 457 (8th Cir.), cert. denied, 491 U.S. 908, 109 S.Ct. 3194, 105 L.Ed.2d 702 (1989). However, appellee argues that these cases are not applicable to this case. Appellee contends that the four claims not properly raised in state court should be procedurally barred based on the analysis of the district court because the circuit's announcement that ineffective post-conviction counsel can constitute cause is a “new rule” that occurred after Schlup’s federal habeas action. According to appellee, applying this “new rule” to this appeal would violate the prohibition in Teague v. Lane, 489 U.S. 288, 109 S.Ct. 1060, 103 *639L.Ed.2d 334 (1989). Because we will address the merits of trial counsel’s performance, resolution of the procedural bar issue is unnecessary.
. The dissent argues that trial counsel was ineffective in failing to consult psychiatrists or psychologists who had treated Schlup for a drug problem and that admission of this and other expert psychiatric or psychological testimony may have changed Schlup’s sentence. However, our finding that the lack of expert psychiatric or psychological evidence did not prejudice Schlup’s case is made in the context of numerous aggravating circumstances (rather than the single aggravating circumstance referenced by the dissent) and admission of lay testimony describing Schlup’s horrible childhood.
In any event, Schlup’s assertion that trial counsel was ineffective in failing to offer expert psychiatric or psychological testimony is subject to procedural bar, despite our decision to dispose of the issue on its merits. "Cause” to justify a procedural default under the cause and prejudice standard must be external to the petitioner. Although counsel's ineffectiveness can be cause, the ineffectiveness must "constitute[ ] a violation of petitioner’s right to counsel, so that the error [can] be seen as an external factor, i.e., ‘imputed to the State.’ ” Coleman v. *640Thompson, — U.S. -, -, 111 S.Ct. 2546, 2567, 115 L.Ed.2d 640 (1991) (citations omitted). Schlup did not raise the mitigating evidence issue on direct appeal of his conviction and sentence, and Schlup did not have a constitutional right to counsel in his post-conviction proceedings. See Pennsylvania v. Finley, 481 U.S. 551, 107 S.Ct. 1990, 95 L.Ed.2d 539 (1987); Murray v. Giarratano, 492 U.S. 1, 109 S.Ct. 2765, 106 L.Ed.2d 1 (1989). Moreover, giving Schlup the benefit of a broad reading of Coleman, which addressed but left undecided the possibility that an indigent defendant may have a constitutional right to counsel in "the first forum in which a federal claim can be raised," Coleman, — U.S. at-, 111 S.Ct. at 2567, would not change the conclusion that Schlup’s mitigating evidence claim is procedurally barred. See State v. Wheat, 775 S.W.2d 155, 158 (Mo.1989) (Blackmar, C.J., dissenting) (explaining that Missouri case law under Rule 27.26 allowed ineffectiveness claims to be presented on appeal from the judgment of conviction only if they could be disposed of on the record, but that such claims were ordinarily not ripe for presentation until post-conviction proceedings). Schlup failed to raise this claim in his 27.26 proceedings (neither his 27.26 motion nor the 27.26 court order addresses this issue) and he did not raise it on appeal of the 27.26 order. Thus, Schlup’s failure to properly raise in state court the claim that trial counsel was ineffective in failing to investigate expert psychiatric or psychological evidence is not attributable to a cause external to his defense and cannot constitute cause to justify the procedural default.
. This finding was not in response to a claim raised by Schlup before the state court, but pursuant to the Missouri Supreme Court’s statutory duty to review the imposition of the death sentence. Schlup, 724 S.W.2d at 242.
