Defendant-appellant David R. Knoll appeals from a decision and order entered April 28, 1995, in the United States District Court for the Western District of New York (William M. Skretny, Judge), denying Knoll’s motion to suppress evidence introduced against him at trial. The district court issued its decision and order on remand from this court following Knoll’s appeal from a judgment entered September 28, 1992, convicting him of one count of aiding and abetting the making of a material false statement tо a department of the United States in violation of 18 U.S.C. §§ 1001 and 2. We affirm the district court’s evidentiary ruling.
Knoll also challenges the validity of his conviction under
United States v. Gaudin,
I
The facts pertaining to this appeal are described in the distriсt court’s opinion denying Knoll’s pre-trial motion to suppress,
United States v. Gleave,
*996
On February 22, 1990, Knoll was indicted on, among other things, one count of aiding and abetting his co-defendant Ted W. Gleave in making a material false statement to a department of the United States in violation of 18 U.S.C. §§ 1001 and 2 (“Count Eight”).
1
Count Eight charged that, in June 1987, Knoll assisted Gleave in the preparation of a financial statement for the United States Department of Justice (“DOJ”), in which Gleave falsely stated that he did not have a savings account.
Knoll I,
The government’s case against Knoll was based in part on information obtained from files stolen from Knoll’s law office. The files were purloined during a burglary orchestrated in June 1986 by Timothy Ernie, a then-incarcerated felon.
Id.
at 1317. Following the burglary, Ernie contacted Assistant United States Attorney (“AUSA”) Anthony Bruce and informed AUSA Bruce that Ernie could provide evidence of illegal activity by Knoll.
Id.
Ernie’s girlfriend, Patricia Devany, then delivered to AUSA Bruce various documents and tapes that she and Ernie’s associatе, Diane Brown, had removed from the stolen files.
Id.; United States v. Knoll,
No. 90-CR-33S-01, slip op. at 6 (W.D.N.Y. Apr. 28, 1995)
(“Knoll II”).
After receiving the delivery, AUSA Bruce
informed Ernie
that he was disappointed with the materials and told Ernie he would have to “get [him] more information.”
Knoll I,
Knoll filed a pre-trial motion to suppress thе evidence recovered from his stolen files, arguing that its use violated his Fourth Amendment right to be free from unreasonable searches and seizures.
Gleave,
The ease proceeded to trial. In charging the jury on Count Eight, the district court, in accordance with settled Second Circuit law,
see United States v. Elkin,
Knoll appealed, reasserting the Fourth Amendment claim that he raised in his pretrial motion to suppress. We agreed with the district court that the burglary of Knoll’s office occurred without the involvement of the government, and thus did not implicate the Fourth Amendment. However, we concluded that the search of the stolen files following the burglary was an event separate from the burglary.
See Knoll I,
On remand, the district court held a hearing and concluded that the search of Knoll’s files was completed before AUSA Bruce asked Ernie for more information. Specifically, the district court found that Devany and Brown had searched through each of the stolen files immediately after the burglary, removing documents from envelopes and files, looking at letters, listening to tape recordings, and separating and segregating documents, prior to Ernie’s initial contact with AUSA Bruce. Knoll II, slip op. at 10-11. The district court therefore concluded that the object of the search had been completed, and Knoll’s reasonable expectation of privacy breached, before any governmental involvement in the case, thereby placing the search beyond the purview of the Fourth Amendment. Id. at 11-12. Knoll once again appealed.
On June 19, 1995, two months after the district court’s decision on the remanded suppression issue and one month after Knoll filed his notice of appeal, the Supreme Court decided Gaudin.
2
The Court held in
Gaudin
that the failure to submit the question of materiality to the jury in a § 1001 prosecution violates a defendant’s “right to hаve a jury determine, beyond a reasonable doubt, his guilt of every element of the crime with which he is charged.”
Gaudin,
515 U.S. at -,
II
A. Knoll’s Fourth Amendment Claim
The district court held an evidentiary hearing and concluded that the search of Knob’s files was completed prior to the government’s involvement in the case. This is precisely the inquiry that we requested in
Knoll I.
Accordingly, we wib not disturb the district court’s conclusion unless it rests upon clearly erroneous factual findings.
See United States v. Brown,
The district court’s findings were based largely on its assessment of the credibihty of the confliсting testimony of the witnesses. We find no error in the court’s decision to discount portions of Ernie’s testimony and credit instead the testimony of Devany and Brown.
See United States v. Davis,
We also reject Knoll’s contention that the government’s continued possession of the files after they were turned over to AUSA Bruce constituted an illegal seizure. This argument was not raised in the district court,
see
Br. of Def.-Appellant at 42 n.20, and thus we review this argument pursuant to Fed. R. Crim P. 52(b) for plain error. We find no error at all, much less plain error in the government’s continued possession of the files. The government was entitled to retain and hold for subsequent use the evidence in its possession as a result of the private search in this case.
See Walter v. United States,
B. The Claim of Gaudin Error
Knoll challenges the validity of his conviction in light of the failure of thе trial judge to submit the question of materiality to the jury as subsequently required by Gaudin. This. challenge is raised before this court in a supplemental brief filed after the district court denied his § 2255 motion. In the unique procedural posture of this case, we choose to exercise our discretion and review the Gaudin error as if it were raised for the first time on direct appeal instead of on a collateral challenge to his conviction.
The parties agree that the district court’s failure to submit to the jury the question of the materiality of Gleave’s false statement violated Knoll’s right to have a jury determine, beyond a reasonable doubt, his guilt as to each element of the charged offense.
See Gaudin,
515 U.S. at-,
1. Johnson v. United States
In
Johnson,
the Supreme Court addressed the issue of the appropriate standard for reviewing on direct appeal a
Gaudin
error that occurred at trial without objection by the defendant.
4
Johnson was indicted for perjury after testifying falsely before a grand jury as to the source of funds for various real estate purchases. At trial, in accordance with settled Eleventh Circuit law, the district court instructed the jury that the element of materiality was a question for the judge to decide. Johnson did not object. Before Johnson’s appeal, the Supreme Court decided
Gaudin.
On appeal, the Court of Appeals for the Eleventh Circuit reviewed for plain error under Fed. R. Crim P. 52(b)
5
and declined to reverse the conviction because the error did not affect Johnson’s “substantial rights.”
See Johnson,
- U.S. at-,
The Supreme Court granted certiorari to resolve the circuit split between the Ninth Circuit’s
en banc
decision in
United States v. Keys,
Thus, the Court applied plain error review under Rule 52(b) as outlined in
United States v. Olano,
The Court found that there was “error” under the first prong of
Olano
because
Gau-din
applies retroactively on direct review and the trial court erred by failing to submit the question of materiality to the jury.
Johnson,
- U.S. at -,
Under the third prong of
Olano,
the “plain error” must also “affect substantial rights.”
The final requirement of Olano requires an appellate court to determine whether the forfeited error “seriously affect[s] the fairness, integrity or public reputation of judicial proceedings before it may exercise its discretion to correct the error.” Id. (internal quotations omitted). In Johnson’s case, the evidence supporting materiality was “overwhеlming.” Id. The grand jury was investigating her boyfriend’s alleged narcotics activity and the disposition of the proceeds of that activity, including the possible concealment of such proceeds as real estate investments. Johnson presented no plausible argument that lying about the source of money to improve her home was “somehow not material to the grand jury investigation.” Id. The Court concluded that there was no basis for finding that the error satisfied the final prong of Olano, .stating:
On this record there is no basis for concluding that the error “seriously af-.. feet[ed] the fairness, integrity or public reputation of judicial proceedings.” Indeed, it would be the reversal of a conviction such as this which would have that effect. “Reversal for error, regardless of *1000 its effect on the judgment, encourages litigants to abuse the judicial process and bestirs the public to ridicule it.” R. Traynor, The Riddle of Harmless Error 50 (1970). No “miscarriage of justice” will result here if wе do not notice the error, Olano,507 U.S. at 736 ,113 S.Ct. at 1779 , and we decline to do so.

2. Applying Johnson to Knoll’s Claims
Despite the near identity of the issue in
Johnson
and this appeal, Knoll contends that
Johnson
does not govern our decision. He asserts that under our decision in
United States v. Tillem,
Knoll’s argument that
Johnson
does not address whether Rule 52(a) or 52(b) provides the applicable standard when a “solid wall of circuit authority” makes the objection at trial futile is meritless. Knoll relies heavily on the Ninth Circuit’s decision in
Keys.
In
Keys,
the Ninth Circuit, sitting
en banc,
addressed the same materiality question at issue in this case and in
Johnson. Keys
held that Rule 52(a) governs appellate review of unpre-served
Gaudin
error on direct аppeal because “where a defendant faced with a solid wall of authority endorsing a jury instruction acquiesces in or fails to object to it, that defendant is entitled on appeal to the benefit of the new rule without being held to plain error standards.”
Keys,
Knoll’s assertion thаt Second Circuit precedent requires review under Rule 52(a) is frivolous.
See United States v. Ballistrea,
Knoll argues in the alternative that a “modified” plain error review under Rule 52(b) applies to his case under our decision in
Viola. See
As in
Johnson,
the first two prongs of
Olano
are satisfied in this case. The failure to submit materiality to the jury was “error” and the error is “plain” at the time of appellate consideration in this case. Following the Supreme Court’s lead in
Johnson,
we decline to address
Olano’s
third prong because even if Knoll satisfies the third prong of
Olano,
Knoll fails to satisfy
Olano’s
final requiremеnt that the error “seriously a£fect[ed] the fairness, integrity or public reputation of judicial proceedings.”
Olano,
This requirement, not expressly set forth in Rule 52(b), “guide[s] the exercise of remedial discretion [by courts of appeal] under Rule 52(b).”
Id.
at 736-37,
The facts of this case do not satisfy the final requirement of
Olano.
As we discussed in
Knoll I,
in 1987, DOJ sought to collect an outstanding $6,000 criminal fine owed by Gleavе as a result of prior unlawful activity. On June 2, 1987, Knoll and Gleave met with DOJ personnel and provided information to complete a “Financial Statement of Debtor” form.
Knoll I,
31. . Q. Do you have a savings account?
A. No.
We have no doubt that the knowledge that Gleave maintained this account would be material to the DOJ’s efforts to collect the fine. We found in
Knoll I
that there was “sufficient proof for the jury to find the Cayman account was an unrevealed savings account.”
Knoll I,
Instead of confronting the materiality point directly, Knoll recycles arguments resolved against him in
Knoll I.
Knoll contends that there is an issue of whose money was actually in the account. This exact argument was rejected in
Knoll I,
We are unable to discern any basis for finding that concealing this account was somehow not material when made to an agency seeking to collect a fine. Thus, we are unable to conclude that in not submitting the materiality issue to the jury “the error seriously affected the fairness, integrity or public reputation of judicial proceedings.”
CONCLUSION
We affirm the district court’s ruling that appellant’s Fourth Amendment rights were not violated. We also hold that because the failure to submit the issue of materiality to the jury did not “seriously affect the fairness, integrity or public reputation of judicial proceedings,” it need not be corrected under Rule 52(b). The judgment of conviction is affirmed.

. The Supreme Court did not decide in
Gaudin
whether, in a case in which the judge decided the issue of materiality, the government should be given the opportunity to show that the error was harmless. Noting that “there is a ‘strong presumption' that a constitutional violation will be subject to harmless-error analysis,” three concurring Justices in
Gaudin
thought harmless-error analysis should apply. 515 U.S. at-,

Rule 52. Harmless Error and Plain Error
(a) Harmless Error. Any error, defect, irregularity or variance which does not affect substantial rights shall be disregarded.
(b) Plain Error. Plain errors or defects affecting substantial rights may be noticed although they were not brought to the attention of the court.
