Defendant Mary Alice Wolf was convicted of three counts of traveling “in interstate or foreign commerce ... with intent that a murder be committed,” 18 U.S.C. § 1952A, and one count of conspiring to commit that offense, 18 U.S.C. § 371. In an unpublished order filed March 15, 1988, we affirmed the conviction. On October 3, 1988, the Supreme Court, — U.S. -, 109 S.Ct. 39, 102 L.Ed.2d 18, granted Wolf’s petition for a writ of certiorari, vacated our order and remanded for further consideration in light of the Court’s recent decision in Arizona v. Roberson, — U.S. -, 108 S.Ct. 2093, 100 L.Ed.2d 704 (1988). We now hold that admission of defendant’s confession violated the prophylactic rule of Roberson and was not harmless beyond a reasonable doubt; therefore, we reverse and remand for a new trial.
I.
On the morning of May 27, 1986, Wolf appeared before a Jefferson County, Kentucky, District Court on two charges: theft by failure to make required restitution, for which she was being arraigned; and criminal possession of a forged instrument, for which she had already been arraigned and for which she had been appointed counsel. During the hearing, Wolf was asked if she had an attorney to represent her or if she wanted one appointed. Wolf requested an attorney, and the hearing judge ordered *1322that a public defense attorney be appointed to represent her on the theft charge.
After the hearing, Wolf was returned to the Women’s Jail in Louisville, Kentucky, where she had spent the previous night. Later that day, while still in custody and before she had spoken to an attorney, Wolf was visited by two agents of the United States Bureau of Alcohol, Tobacco, and Firearms (ATF). At the outset of the meeting, the agents advised Wolf of her rights under Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966); she then signed a form stating she understood and wished to waive those rights. Wolf then confessed to her involvement in a scheme to kill Vicki Brashear, the wife of a former boyfriend, Alan Brashear.
On September 3, 1986, a federal grand jury in the Eastern District of Kentucky indicted Wolf and seven codefendants for offenses arising out of the scheme to murder Vicki Brashear. Wolf filed a pretrial motion to suppress her confession, arguing that it was involuntary and obtained in violation of the fifth and sixth amendments. Rejecting allegations that the confession was coerced, the district court denied Wolfs motion.
A recording of the confession was played to the jury once during Wolfs trial, and again at the request of the jury during its deliberations. The United States also relied upon the confession several times during its closing arguments. Wolf was subsequently convicted. On appeal, Wolf reasserted her claim that the confession was involuntary and obtained in violation of the fifth and sixth amendments. We rejected those claims and affirmed the conviction. After the Supreme Court vacated our order and remanded for further consideration, we requested supplemental briefing on the fifth amendment issue raised by Roberson. Wolf now urges us to reverse her conviction in light of the Supreme Court’s holding in that case.
II.
A suspect who has “expressed his desire to deal with the police only through counsel [ ] is not subject to further interrogation by the authorities until counsel has been made available to him, unless the accused himself initiates further communications, exchanges or conversations with the police.” Edwards v. Arizona, 451 U.S. 477, 484-85, 101 S.Ct. 1880, 1885, 68 L.Ed.2d 378 (1981). In Roberson, supra, the Supreme Court held that this prophylactic rule applies when a police-initiated interrogation following a suspect’s request for counsel occurs in the context of an unrelated criminal investigation. 108 S.Ct. at 2096.1
We find that on the facts of this case Roberson was violated: Wolf invoked her fifth amendment right to counsel at the arraignment; she remained in custody and did not consult with her attorney from that time until after she gave her statement; and the ATF agents, not Wolf, initiated the interrogation that resulted in the statement.
The United States claims that defendant’s request for counsel at arraignment did not trigger the protections of Roberson because it was not made during a custodial interrogation. In other words, the United States argues that while such a request invokes the sixth amendment right to counsel, it does not invoke the prophylaxis of having an attorney present to protect the fifth amendment right against self-incrimination. We reject this contention.
Our opinion in Boles v. Foltz, 816 F.2d 1132 (6th Cir.1987), in which we addressed a similar question for purposes of an Edwards analysis, provides some support for the claim raised by the United States. In Boles, our court held that a defendant’s statement at arraignment that he had an attorney did not express “his desire to deal with the police only through counsel.” Id. at 1135 (quoting Edwards, 451 U.S. at 484, 101 S.Ct. at 1885). Our court reasoned:
*1323Although the law does not require a defendant to indicate whether a request for counsel is based on the fifth amendment privilege against self-incrimination or the sixth amendment right to be represented by counsel during judicial proceedings, Michigan v. Jackson, 475 U.S. 625 [, 106 S.Ct. 1404, 89 L.Ed.2d 631] ... (1986), where it is clear that the defendant’s request is for something other than the presence of an attorney during interrogation the request should be so construed.
Boles, 816 F.2d at 1135. Relying on Connecticut v. Barrett, 479 U.S. 523, 107 S.Ct. 828, 93 L.Ed.2d 920 (1987), we further noted that in determining whether a defendant has invoked his right to counsel, ambiguous statements are to be given broad interpretation, but the ordinary meaning of a defendant’s statement is not to be disregarded. Considering the context in which the statement was made, we concluded that the ordinary meaning of Boles’ statement was that he “wished to have his attorney present at the preliminary hearing.” Id.
However, Boles is distinguishable from this case. In concluding that the ordinary meaning of Boles’ statement was that he wanted to have his attorney present at an upcoming preliminary hearing, our court relied on evidence in the record that his statement was made as part of an exchange setting up that hearing. Here, there is no similar evidence that Wolf intended to limit her invocation of her right to counsel. At Wolf’s arraignment, the prosecutor simply read the charge and Wolf requested appointed counsel. Given the absence of comparable evidence indicating that Wolf intended to limit her request to the invocation of the sixth amendment right to counsel, we resolve any doubts as to her intent in favor of protecting her Constitutional claim, Jackson, 475 U.S. at 633, 106 S.Ct. at 1409, and we find that her request at arraignment triggered the prophylactic rule of Roberson. Cf. Cervi v. Kemp, 855 F.2d 702, 706-07 (11th Cir.1988) (applying Edwards and holding that request for counsel made at arraignment is an assertion of fifth amendment right to counsel); United States v. Fairman, 813 F.2d 117 (7th Cir.1987) (invocation of right to counsel at arraignment triggers Edwards ).
III.
The United States further argues that even if the trial court’s decision to admit Wolf’s confession violated Roberson, the violation does not require reversal because it was harmless error. See Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967). We agree with the United States that the harmless error standard of Chapman is the proper measure of our scrutiny. Appellate courts, including our own, have applied the harmless error analysis to confessions admitted in violation of the related rules of Edwards and Miranda. See, e.g., Rose v. Engle, 722 F.2d 1277 (6th Cir.1983) (admission of statement obtained in violation of Edwards not harmless error); Christopher v. Florida, 824 F.2d 836 (11th Cir.1987) (admission of statement obtained in violation of Edwards is reversible error). In doing so, these courts have recognized, either implicitly or explicitly that, while the admission of a truly coerced confession can never be harmless error, Chapman, 386 U.S. at 23, 87 S.Ct. at 827, the erroneous admission of an otherwise voluntary confession obtained in violation of the prophylactic rules of Miranda and its progeny can be harmless. See United States v. Charlton, 565 F.2d 86, 92 (6th Cir.1977); Christopher, 824 F.2d at 847-48. We believe this approach is consistent with the Supreme Court’s prohibition on the use of a harmless error analysis in cases where the right violated is so basic that the violation affects the likelihood of the defendant receiving a fair trial. Cf. Chapman, supra; Gray v. Mississippi, 481 U.S. 648, 107 S.Ct. 2045, 95 L.Ed.2d 622 (1987) (because violation of the right to an impartial jury goes to the very integrity of the legal system, Chapman harmless error analysis cannot apply) (plurality); Rose v. Clark, 478 U.S. 570, 577-78, 106 S.Ct. 3101, 3106, 92 L.Ed.2d 460 (1986) (“Without these basic protections a criminal trial cannot reliably serve its function as a vehicle for determination of guilt or innocence, and no *1324criminal punishment may be regarded as fundamentally fair.”).
Applying this analysis to the Roberson violation in this case, requires us to determine: (1) whether the confession, although unlawfully admitted, was otherwise voluntary; and if so, (2) whether admission was harmless error. Cf. Christopher, 824 F.2d at 846 n. 23; Charlton, 565 F.2d at 92-93. Because we conclude that the admission of Wolfs unlawful confession was not harmless error, we need not address the first question in this case.
To determine whether the error was harmless under Chapman, the question this court must ask is whether, absent the improperly admitted confession, it is clear beyond a reasonable doubt that the jury would have returned a verdict of guilty. United States v. Mahar, 801 F.2d 1477, 1500 (6th Cir.1986). Because juries consider confessions extremely probative of guilt, some courts recognize that admission of an unlawfully obtained confession can rarely be harmless error. See, e.g., Christopher, 824 F.2d at 846 (“We have ruled the admission of an unlawful confession harmless only in limited instances, such as where there was in evidence at least one other lawful confession by the defendant.”). Yet,, if the record is clear that the jury’s decision was not affected, we may find the error to be harmless. Murphy, 763 F.2d 202 at 209-10 (6th Cir.1985) (harmless error found where “circumstantial and corroborating evidence was massive”).
After reviewing the entire record in this case, we cannot find that the admission of defendant’s unlawfully obtained confession was harmless beyond a reasonable doubt. This case does not involve cumulative confessions. Instead, the United States argues that because its witnesses testified at trial that on three separate occasions Wolf had admitted her involvement in the scheme to murder Vicki Brash-ear, the improperly admitted confession was cumulative. The United States first relies on the testimony of a co-conspirator, who stated that Wolf had told him that she wanted Vicki Brashear killed to get back at Alan Brashear. Wolf also allegedly asked him, apparently concerned that the “job” would not be done, “you mean I’ve wasted $6000 [an amount allegedly paid to ‘gun for hire’ Richard Savage to murder Vicki Brashear]?” Wolf denied making these statements. The United States next points to the testimony of Deborah Mattingly who lived with Richard Savage and testified that she had learned from Wolf that she repeatedly called Savage because she had hired him to kill Vicki Brashear. Wolf denied talking to Mattingly about Vicki Brashear, and testified that Mattingly was very upset because Wolf, who had become romantically involved with Savage, had “taken” him from Mattingly after a seven-year relationship. The United States also relies on a statement overheard by Timothy Cox, a friend of Wolf from high school, made by Wolf during a visit to his home. Cox testified that Wolf had told Alan Brashear, during a telephone conversation, “I know that you had nothing to do with trying to knock Vicki off; but if it comes to that, I will have to testify with Richard [Savage] against you.” Again, Wolf denied making the statement and also denied talking to Cox about Savage. While our review of the entire record indicates that Wolf’s credibility was at the very least suspect2 we are not satisfied that the statements relied upon by the government, made by witnesses of dubious credibility and directly contradicted by Wolf’s own testimony, would inevitably have led the. jury to return a guilty verdict absent the unlawful confession.
The United States also argues, more generally, that the evidence presented at trial overwhelmingly establishes the details of the offenses charged. Again, evidence and testimony offered by Wolf contradicts much of the evidence presented by the government, and again this case turns in large part on the issue of Wolf’s credibility. Yet, even if this were not so, the record clearly indicates that the now-outlawed confession played too important a role in this case to warrant a finding of harmless er*1325ror. This is particularly so here, where the United States relied on Wolfs confession at least four times during its closing arguments and the jury specifically asked to rehear the recording of the confession during its deliberations.
Accordingly, we REVERSE and REMAND for a new trial consistent with this decision.
. Although Wolf was convicted before Roberson was decided, the Supreme Court’s decision controls our analysis of the fifth amendment claim Wolf has properly raised before our court. Cf. Shea v. Louisiana, 470 U.S. 51, 105 S.Ct. 1065, 84 L.Ed.2d 38 (1985) (rule of Edwards applies to convictions not final at time case was decided).
. Most indicative of Wolfs lack of credibility is the-trial judge's finding, in his Memorandum Opinion and Order denying Wolfs motion to suppress the confession at issue, that her suppression hearing testimony was simply incredible.
