   SUMMARY ORDER

Petitioner-Appellant Israel Weingarten, currently serving a thirty-year sentence following convictions of two counts of transporting a minor in foreign commerce for the purpose of engaging in criminal sexual activity and two counts of travel in foreign commerce for the purpose of engaging in sexual conduct with a minor in violation of 18 U.S.C. § 2423, appeals the District Court’s denial of his petition for relief under 28 U.S.C. § 2255. In an opinion also issued today, we affirm a portion of the District Court’s order pertaining to Weingarten’s statute of limitations defense. We AFFIRM the remaining issues on appeal in this summary order. We assume the parties’ familiarity with the underlying facts and the procedural history, which we reference only as necessary to explain our conclusions.

I. Standard of Review

We review de novo ineffective assistance of counsel claims on an appeal from a denial of relief under § 2255. Puglisi v. United States, 586 F.3d 209, 215 (2d Cir. 2009). We also review de novo prosecutorial misconduct claims on an appeal from a denial of relief under § 2255. See United States v. Cuervelo, 949 F.2d 559, 567 (2d Cir. 1991).

II. Trial Counsel’s Preparation

Weingarten argues he was denied his Sixth Amendment right to counsel because the District Court forced him to choose between proceeding to trial pro se or with trial counsel with whom Weingar-ten could not effectively communicate. We resolved whether Weingarten was entitled to eve-of-trial relief of counsel in his first direct appeal. We concluded that “the district court conducted a detailed inquiry into Weingarten’s concerns, and after reviewing his complaints and hearing from counsel, adequately satisfied itself that there was neither a complete breakdown of communication nor an irreconcilable conflict.” United States v. Weingarten, 409 Fed.Appx. 433, 436 (2d Cir. 2011). We also held that there was no evidence to suggest the District Court should have granted Weingarten’s belated request for a continuance or relief from counsel after they had represented him ably for months. Id. at 435-36. The arguments Weingarten raises here either were resolved or are implicitly covered by the reasoning of that prior decision. The “law of the case” doctrine therefore bars us from considering their merits on collateral attack. See Yick Man Mui v. United States, 614 F.3d 50, 53 (2d Cir. 2010) (noting that, at the appellate level, “the law of the case rule” bars re-litigation of issues on collateral attack that were “already decided on direct appeal”).

Weingarten also argues that trial counsel were constitutionally ineffective because they did not adequately investigate the facts underlying the allegations in the indictment and otherwise failed to prepare for trial. As the Supreme Court has explained, “counsel has a duty to make reasonable investigations or to make a reasonable decision that makes particular investigations unnecessary.” Strickland v. Washington, 466 U.S. 668, 691, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). In the context of an ineffectiveness claim, “a particular decision not to investigate must be directly assessed for reasonableness in all the circumstances, applying a heavy measure of deference to counsel’s judgments.” Id. Here, the record does not establish that counsel’s conduct in preparing for trial was objectively unreasonable. Counsel litigated Weingarten’s case vigorously ahead of trial, and they made reasonable efforts to work with Weingarten to rebut the government’s case, especially in light of the unique difficulties and circumstances of this trial. See Weingarten, 409 Fed.Appx. at 436 (noting that “Weingarten and his supporters—the persons he referred to throughout trial as ‘his people’—shared much of the blame for any disharmony between Weingarten and his attorneys”). Contrary to Weingarten’s arguments on appeal, the duty to investigate does not “compel defense counsel to investigate comprehensively every lead or possible defense,” nor are counsel required “to scour the globe on the off-chance something will turn up.” Greiner v. Wells, 417 F.3d 305, 321 (2d Cir. 2005).

Finally, the District Court did not err in denying Weingarten’s § 2255 petition without holding an evidentiary hearing. The parties’ extensive written submissions and supporting materials were sufficient for the District Court to adjudicate Wein-garten’s claims of ineffective assistance. See Puglisi, 586 F.3d at 215.

III. Counsel’s Failure to Object at Sentencing

Weingarten argues his counsel at sentencing was ineffective because she failed to object when the District- Court, in Weingarten’s view, punished him for proceeding pro se and for exercising his constitutional right to confront the witnesses against him. In fact, the District Court did not punish Weingarten for proceeding pro se or for cross-examining the Government’s witnesses in fashioning its sentence. Rather, the court, cited the abusive manner in which Weingarten exercised his right of self-representation as context for its sentencing decision. It was reasonable for Weingarten’s counsel to believe that it was proper for the District Court to consider that information. See Strickland, 466 U.S. at 687-88, 104 S.Ct. 2052.

IV. Government Misconduct

Finally, Weingarten argues the Government violated Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), and Napue v. Illinois, 360 U.S. 264, 79 S.Ct. 1173, 3 L.Ed.2d 1217 (1959), by admitting into evidence a handwritten repentance letter found in Weingarten’s pocket, by suggesting to the jury that two members of Weingarten’s religious community, Principal Stauber and Rabbi Weis, corroborated the claims of sexual abuse, and by failing to disclose information about this evidence to the defense.

For Weingarten to prevail on his Brady claim, he must show that (1) the Government suppressed (2) evidence in its possession favorable to the defense (3) resulting in prejudice to his defense. See Banks v. Dretke, 540 U.S. 668, 691, 124 S.Ct. 1256, 157 L.Ed.2d 1166 (2004).

Weingarten argues the Government did not comply with its Brady obligations with respect to the handwritten letter because (a) he told the Government and the Court that he-did not write the letter and (b) because the Government did not disclose to Weingarten a second page of the letter. Weingarten cannot make out a Brady claim on a theory that the Government suppressed statements Weingar-ten himself made. See DiSimone v. Phillips, 461 F.3d 181, 197 (2d Cir. 2006) (“Evidence is not ‘suppressed’ if the defendant either knew, or should have known, of the essential facts permitting him to take advantage of any exculpatory evidence.”). Weingarten’s contention that the Government failed to disclose a supposedly exculpatory second page of the letter is speculative and lacks evidentiary support. He merely states that, because the Government has an affirmative duty to investigate fully each prosecution, “[i]t seems likely the [Government learned that Weingarten did not write the letter.” Appellant’s Br. 70. That cannot support a Brady claim. See United States v. Graham, 484 F.3d 413, 417 (6th Cir. 2007) (“Brady clearly does not impose an affirmative duty upon the [G]overnment to take action to discover information which it does not possess.” (quoting United States v. Beaver, 524 F.2d 963, 966 (5th Cir. 1975)); see also Pennsylvania v. Ritchie, 480 U.S. 39, 57, 107 S.Ct. 989, 94 L.Ed.2d 40 (1987) (“[T]he [Government has the obligation to turn over evidence in its possession that is both favorable to the accused and material to guilt or punishment.” (emphasis added)).

Weingarten also contends the Government violated Brady by failing to disclose that Principal Stauber and Rabbi Weiss told FBI agents they doubted Weingar-ten’s daughter’s allegations. “Suppressed impeachment evidence is material if the witness whose testimony is attacked supplied the only evidence linking the defendants) to the crime, or where the likely impact on the witness’s credibility would have undermined a critical element of the prosecution’s case.” United States v. Diaz, 176 F.3d 52, 108 (2d Cir. 1999) (internal quotation marks omitted). Importantly, neither Principal Stauber nor Rabbi Weiss testified at trial, and any suggestion by the Government that these individuals had corroborated the claims of sexual abuse was not the sole evidence linking Weingarten to the abuse. Nor are we persuaded that these two uncorroborated statements would have sufficiently undermined Wein-garteris daughter’s testimony regarding his sexual abuse.

To prevail on his Napue claim, Weingar-ten must prove, inter alia, the Government knowingly allowed false evidence to be admitted. See United States v. Vozzella, 124 F.3d 389, 393 (2d Cir. 1997). As noted above, Weingarten provides only speculation—not proof—that the Government knew he did not write the handwritten repentance letter. And Weingarten fails to show the record evidence pertaining to Principal Stauber and Rabbi Weiss was false.

V. Conclusion

We have considered Weingarten’s remaining arguments and identify no basis for reversal. The order of the District Court is therefore AFFIRMED. 
      
      . In addition to the statute of limitations issue, this Court granted Weingarten’s motion for a certificate of appealability to address: (1) whether trial counsel rendered ineffective assistance in failing to prepare for trial and failing to object to the District Court's consideration of Weingarten’s pro se cross-examination conduct in imposing sentence, and (2) whether alleged government misconduct deprived Weingarten of a fair trial.
