This is one of two appeals now before this court arising from preliminary proceedings in the prosecution of Jackie Presser, the president, and two other officials of the Teamsters Union. Neither appeal involves matters directly related to the question of the guilt or innocence of the defendants. The appellants in both cases seek media access to the sealed records of certain pretrial proceedings that were conducted in camera by the district court. The companion case, decided this date, is No. 86-3735 in which the National Broadcasting Company, Inc. and WKYC-TV3 are the appellants (the NBC appeal).
I.
A.
The indictment, charging the defendants with embezzlement of union funds, was filed in the United States District Court for the Northern District of Ohio on May 16, 1986. The case was assigned by blind draw to District Judge Ann Aldrich. Following the disqualification of Judge Aid-rich, which is dealt with in the NBC appeal, the case was returned to the clerk of court and assigned to District Judge John M. Manos on June 4. Judge Manos recused himself on June 17 and the case was reassigned to District Judge George W. White.
After the case was assigned to Judge White, Storer Communications, Inc. and WJW-TV8 (Storer) intervened and filed a motion to unseal all documents related to Judge Manos’s recusal. Storer asserted that the government lawyers had gone to Judge Manos on June 16, without notice to defendants’ counsel, and had shown documents to Judge Manos which caused him to recuse himself. Storer sought access to all materials upon which Judge Manos based his recusal.
Judge White scheduled an in camera hearing for June 26 on the motions of NBC and Storer to unseal various materials, including those related to Judge Manos’s re*332cusal. On June 26 an attorney for the Department of Justice wrote the attorneys for the three defendants, advising them that the government had filed certain materials in camera and under seal with Judge White. The letter stated that the “filing” contained the materials which the government had furnished Judge Manos when he was assigned the case. The record shows that the government filed the materials on June 26 at 12:24 p.m. with a covering document styled “Submission of Arguably Producible Materials Under Giglio v. United States.” In this court the government has expanded its argument to contend that the documents shown to Judge Manos were “arguably Giglio-Brady ” materials.
This document, which was addressed to Judge White, stated that the credibility of Allen Friedman would be an issue in the Presser trial and that the government had an obligation to furnish evidence bearing on his credibility. This document urged the court to rule that the materials purportedly related to Allen Friedman’s credibility need not be disclosed to the defendants. The document also stated that unless the court ordered it to do so, the government did not intend to furnish the materials involving Friedman to the defendants. Enclosed with the documents that had been shown to Judge Manos was the transcript of a grand jury proceeding held in Cleveland on December 7, 1983 at which Allen Friedman had testified. The covering document stated that this transcript was included “so that the court may judge the relevance or rather lack thereof, of the Allen Friedman assertions” detailed in the other materials. Allen Friedman’s grand jury testimony dealt with events that occurred between 1966 and 1973, was not exculpatory with respect to the charges against Presser and his codefendants, and did not mention Judge Manos.
B.
Confusion reigned at the June 26 hearing before Judge White. In addition to the government’s ex parte meeting with Judge Manos on June 16, there had been a scheduled conference with Judge Manos on June 17. The government and all defendants were represented by counsel at that conference, at the conclusion of which Judge Ma-nos announced his recusal. At the beginning of Judge White’s hearing on June 26, it appeared that the court was not aware that there had been two meetings. What developed was that no court reporter had been present at either meeting with Judge Manos, and there were no record entries with respect to either meeting except for the order returning the case to the clerk for reassignment.
When it became clear that Storer’s motion referred only to the materials presented to Judge Manos at the ex parte meeting on June 16, Judge White indicated that he did not believe the materials had been filed. In the order denying Storer’s motion, Judge White wrote, “This court is not aware of any material relating to any alleged ex parte hearing held by Judge Ma-nos and the court’s file does not reflect the aforementioned material.” In fact, according to the clerk’s date-time stamp the government had filed that material at 12:24 p.m. on the date of the hearing. The hearing began at 1:00 p.m. on June 26 and Judge White’s denial order was entered the following day. None of the government attorneys advised Judge White that the materials had been filed, and he appears to have based the conclusion that he lacked jurisdiction over Storer’s motion on the assumption that the materials sought by Storer had never been placed in the district court’s hands.
The confusion continued in this court. Approximately one week before the scheduled hearing on the Storer and NBC appeals, NBC made a motion in this court that its counsel, in preparation for oral argument, be permitted to examine materials in the file that had been sealed by Judge White. The court undertook to examine the sealed materials in order to respond to this motion. The district court had not made separate files with respect to the ancillary motions of NBC and Storer. As a result, all matters relating to their motions were placed in the record of the underlying criminal case, and two volumes of that record were transmitted to the *333court of appeals when NBC and Storer appealed the denial of their motions. All of the individually sealed materials appeared to be in volume 2 of the district court record, or in separate sealed cartons. The court left all of these materials under seal. Some of the parties had filed joint appendices and briefs under seal in this court, a practice the court does not permit. The court entered an order denying NBC’s motion, but removing the seal from the portions of the district court record not separately sealed by the order of Judge White, and from the briefs. One volume of the joint appendix was left sealed because it contained a copy of a sealed transcript.
During oral argument of the Storer appeal, the court questioned counsel for the government regarding the whereabouts of the materials that had been submitted to Judge Manos on June 16, since they were not among the materials in volume 2 of the district court record or in the separate sealed cartons previously examined by the court. Counsel responded that she had not included the materials “in the sealed appendix,” and offered to file them with the court under seal “tomorrow when I get back to Washington.” Obviously, the Department of Justice’s left hand did not know what its right hand was doing. As previously noted, the materials had been filed in the district court on June 26. They had been placed in a sealed envelope in volume 1 of the district court record and had been transmitted to the court of appeals. The materials were in the records room of the court of appeals at the very time the government lawyer was advising the court that she would send them “tomorrow.”
C.
The events described in Part I-B are not dispositive of this appeal. They are recited at length to illustrate the difficulties that may result from efforts to close court proceedings. Courts should operate in the open, except where closed hearings are essential to guarantee a fair trial or to protect the integrity of the judicial process. In this case, ultimately the entire district court record, including docket sheets, was transmitted to the court of appeals under seal. Sealed materials should be segregated and clearly identified when transmitting a record to the court of appeals. There must also be better communications within the Department of Justice. In the district court, government lawyers permitted Judge White to rule on the assumption that materials which were the subject of Storer’s motion were not in the court’s records, when they had been filed by the government on the very day of the hearing. On appeal, a government attorney represented to a panel of this court that the same materials were still not in the court’s possession, when in fact the materials had been transmitted as part of the district court record.
II.
On appeal from denial of its motion for access to the “Manos materials,” Storer argues that there is a presumption of openness in all judicial proceedings that should apply to recusal matters. It maintains that the public has a legitimate interest in knowing how a given case becomes the responsibility of a particular judge and a need to know if there are facts which disqualify a judge from hearing a case. Storer contends that the government engaged in blatant “judge-shopping” in inducing Judge Manos to recuse himself, and that the claim that its purpose was to obtain a ruling on “arguably Giglio-Brady ” material is disingenuous.
The defendants assert that if the government did present Giglio-Brady materials to Judge Manos, the defendants would be entitled to have copies but the press has no right to discover them.
The government argues that there is no presumption of openness with respect to either recusal or Giglio-Brady materials. Traditionally, the government maintains, the courts have not opened proceedings involving recusal or proceedings seeking preliminary rulings on arguably GiglioBrady materials. There is no absolute right for the public or press to have access to all preliminary proceedings in a criminal *334prosecution, the government argues, and Storer has not identified factors in this case which trigger a presumption of openness.

A.
In Brady v. Maryland, 373 U.S. 83, 87, 83 S.Ct. 1194, 1196, 10 L.Ed.2d 215 (1963), the Supreme Court held that “the suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.” In Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972), the Court applied the Brady doctrine to a situation where the prosecution withheld from the jury the fact that it had promised a key witness that he would not be prosecuted for his part in a crime if he testified against his companion. The Court found that this witness’s credibility would be an issue, and the jury was entitled to know of the “deal.” Therefore, it was a violation of due process to keep the jury in the dark when the defense sought to establish that there had been an agreement. Id. at 155, 92 S.Ct. at 766.
In United States v. Agurs, 427 U.S. 97, 96 S.Ct. 2392, 49 L.Ed.2d 342 (1976), the Supreme Court identified three different situations in which Brady applies. The Court described these situations and the various effects of a prosecutor’s failure to disclose as follows:
1. The undisclosed evidence demonstrates that the prosecution’s case includes perjured testimony and the prosecution knew, or should have known, that it was perjured. In these cases, the defendant’s conviction will be set aside if there is any reasonable likelihood that the perjured testimony affected the verdict. Id. at 103, 96 S.Ct. at 2397.
2. The defense makes a pretrial request for specific evidence, which is withheld, and the evidence is material in the sense that it might have affected the outcome of the trial, with respect to either the guilt or innocence of the accused, or the issue of punishment. If the evidence is material to the single issue of punishment, then due process only requires a new trial on that issue. Id. at 104, 96 S.Ct. at 2397.
3. There is exculpatory information in the possession of the prosecution which is unknown to defense counsel, and defense counsel either makes no request or makes a general request for all exculpatory material or all “Brady material.” If the defense discovers any evidence after trial that fits this third situation, and the omitted evidence creates a reasonable doubt that did not otherwise exist, then a motion for a new trial must be granted on due process grounds. Id. at 106-07, 96 S.Ct. at 2399.
B.
The government contends that it submitted the sealed materials to Judge Manos “in an excess of caution,” seeking his determination of whether it was required to furnish copies to the defense. Several courts of appeals have approved the practice of prosecutors submitting possible Brady materials in camera to the trial court in order to obtain a pretrial determination of whether disclosure is required. E.g., United States v. Tucker, 773 F.2d 136, 141 (7th Cir.1985) (“the government acted prudently, [in submitting reports of a government informant concerning other misdeeds of a defendant] since if had not submitted the documents for the judge’s inspection it might have opened itself up to a later attack for violating the defendants’ rights under” the Brady doctrine); United States v. Dupuy, 760 F.2d 1492, 1501 (9th Cir.1985) (consultation with trial judge is “particularly appropriate” where government has legitimate reasons for preserving confidentiality of materials submitted); United States v. Holmes, 722 F.2d 37, 41 (4th Cir.1983) (prosecutor has obligation to submit material to the trial court in camera if he has any doubt about whether it might be exculpatory).
Our examination of the materials submitted first to Judge Manos and later to Judge White reveals that they include no evidence of perjury and contain nothing *335exculpatory with respect to the charges against Presser or his co-defendants. There is even less basis for considering the materials to be covered by Giglio. Allen Friedman had already been convicted for accepting payments from a union as a “ghost” employee, and was awaiting sentencing when he gave a statement to the government. The fact that Friedman’s credibility would be an issue at the Presser trial is beside the point. Every witness’s credibility is an issue at trial, to a greater or lesser extent, and the jury is the judge of each witness’s credibility. Giglio comes into play only when the prosecution withholds material information from the jury bearing directly on the credibility of a government witness. Giglio does not require, or permit, the prosecution to obtain a pretrial determination by the judge on the general credibility of its witnesses. The government’s Giglio argument to this court is patently frivolous.
C.
Although our examination of the documents raises serious questions about the true reasons for presenting the sealed materials to Judge Manos, we accept the government’s statement that it acted in an “excess of caution.” Nevertheless, we do not approve the practice of government counsel in a criminal prosecution approaching the trial judge ex parte in any matter related to the pending case. Materials can be submitted to the court in camera, but defense counsel and the public should have notice of the in camera proceedings and an opportunity to seek and argue for an open hearing. The public has a legitimate interest in criminal proceedings, and this interest is thwarted by ex parte proceedings. Motions for closure of criminal proceedings, both before and during the trial, must be posted promptly on the docket sheet, thus giving notice to the public. When such motions are posted, media organizations may move to intervene for the purpose of contesting closure of hearings and the sealing of documents. See United States v. Criden, 675 F.2d 550, 555, 559 (3d Cir.1982) (motions for closure of pretrial criminal proceedings must be docketed sufficiently in advance of hearing on or disposition of such motions to afford interested members of the public an opportunity to intervene and present their views). We have previously cited Criden with approval, In re Knoxville News-Sentinal Co., 723 F.2d 470, 474 (6th Cir.1983), and now adopt its formulation for providing notice and an opportunity for the public to present claims of First Amendment rights of access to pretrial criminal proceedings. The Second Circuit adopted the Criden requirements in Application of the The Herald Company, 734 F.2d 93, 102 (2d Cir.1984). After giving defense counsel and media representatives an opportunity to be heard, the court can then proceed to consider the submitted materials in camera if that is required. Ex parte proceedings, particularly in criminal cases, are contrary to the most basic concepts of American justice and should not be permitted except possibly in most extraordinary cases involving national security. This is not such a case.
A district court has no obligation to conduct a general in camera search of the prosecutor’s files for Brady material. United States v. Holmes, 722 F.2d at 41. It is the duty of the prosecutor, not the court, to disclose exculpatory material. United States v. Dupuy, 760 F.2d at 1504 (Ferguson, J., concurring). However, when a prosecutor presents material to the court for a Brady determination, the court has an obligation to examine the material in camera and determine whether disclosure to the defense is required. Id. at 1503. Accordingly, upon remand, Judge White will examine the materials and make the required Brady determination. There is no Giglio issue in this case.
The district court clearly erred in holding that it had no jurisdiction to rule on Storer’s motion. The underlying cases had been assigned to Judge White and, unbeknownst to him, the materials had been filed in the record along with the government’s statement that they were arguably required to be provided to the defense. Upon remand, if the district court determines that the materials must be disclosed *336to the defense under Brady that determination will not dispose of the Storer motion. Brady requires disclosure of information to the defense, and does not speak to the question of public or media access.
IV.
A.
As the Supreme Court has repeatedly emphasized, there is a strong presumption of openness in criminal trials. E.g., Press-Enterprise Co. v. Superior Court of California, 464 U.S. 501, 104 S.Ct. 819, 78 L.Ed.2d 629 (1984) (Press-Enterprise I); Richmond Newspapers, Inc. v. Virginia, 448 U.S. 555,100 S.Ct. 2814, 65 L.Ed.2d 973 (1980). In Press-Enterprise Co. v. Superior Court of California, — U.S. -, 106 S.Ct. 2735, 92 L.Ed.2d 1 (1986) (Press-Enterprise II) the Supreme Court held that under the First Amendment there is a qualified right of public access to some preliminary proceedings in a criminal prosecution. Two “complementary considerations” determine the right of access to any particular proceeding: (1) “whether the place and process has historically been open to the press and general public,” and (2) “whether public access plays a significant positive role in the functioning of the particular process in question.” Id. 106 S.Ct. at 2740 (citations omitted). If a particular proceeding passes these two tests “of experience and logic,” the right of access which attaches is qualified, not absolute. Id. at 2741. If it is claimed that the right of an accused to a fair trial might be undermined by publicity, “the trial court must determine whether the situation is such that the rights of the accused override the qualified First Amendment right of access.” Id. The Court described this process by quoting language from its earlier opinion in Press-Enterprise I:
“the presumption may be overcome only by an overriding interest based on findings that closure is essential to preserve higher values and is narrowly tailored to serve that interest. The interest is to be articulated along with findings specific enough that a reviewing court can determine whether the closure order was properly entered.” 464 U.S. at 510, 104 S.Ct. at 824.
It is clear that the district court did not consider either the two threshold questions or the ultimate question of access because of its erroneous conclusion that it lacked jurisdiction.
B.
In the NBC appeals we made a distinction between sua sponte recusals and situations where one or more parties seek a judge’s disqualification. The record in the present case makes it clear that at least one reason for submitting the materials to Judge Manos at the June 16 ex parte meeting was to induce him to consider withdrawing. Thus his recusal cannot be considered to have resulted from his own motion. In accordance with our holding in the NBC appeal we conclude that some of the materials are subject to a qualified right of access. This applies to all the submitted materials except the grand jury transcript, which was totally irrelevant either to Judge Manos’s recusal or to the late-discovered Brady rationale for the June 16 meeting. Grand jury proceedings are not conducted in the open, and transcriptions of those proceedings are subject to a rule of secrecy. Rule 6(e)(2), Fed.R.Crim.P. The nature of a grand jury’s work requires that its proceedings remain secret, Douglas Oil Co. v. Petrol Stops Northwest, 441 U.S. 211, 218, 99 S.Ct. 1667, 1672, 60 L.Ed.2d 156 (1979), except where the stringent requirements of Rule 6(e)(3), Fed.R.Crim.P., are satisfied. The grand jury transcript filed under seal by the government will remain under seal.
The remaining materials submitted to Judge Manos and subsequently to Judge White will be treated in accordance with the standards set forth today in the NBC appeals, and the district court will rule on Storer’s application on the basis of specific findings with respect to the defendants’ claim that disclosure of the materials will make it impossible for them to obtain a fair trial.
*337The orders appealed from by Storer are vacated, and the cause is remanded to the district court for further proceedings consistent with this opinion. No costs on appeal.
