OPINION

In 2009, James Murphy was convicted of eontrolled-substance offenses in the United States District Court for the Middle District of Pennsylvania, receiving a lengthy term of incarceration. We affirmed his conviction and sentence. United States v. Murphy, 460 Fed.Appx. 122 (3d Cir. 2012). 1 In February 2012, Murphy filed a “Judicial Complaint and Petition for Misconduct Investigation,” alleging that the indictment in his criminal case “omitted several requirements requisite to its validity and requisite to a grand jury charge and indictment,” such as a “certifying or authenticating form or document.” He also filed two requests for grand jury materials; the first requested a “duplicate copy” of the transcripts for his legal purposes, while the second was a motion for the disclosure of “all of the ministerial grand jury material” pursuant to Fed.R.Crim.P. 6(e)(3)(E)(i), presented without any additional elaboration. The District Court denied his requests in two orders, observing that Murphy had no proceedings pending, presented only speculation regarding the irregularities of the grand jury process, and showed no compelling necessity. Murphy appealed. 2

We have jurisdiction under 28 U.S.C. § 1291. We agree with the District Court that Murphy has not shown any rationale for disclosing additional grand jury proceedings, let alone the “strong” showing generally required. See United States v. Aisenberg, 358 F.3d 1327, 1348 (11th Cir. 2004). Accordingly, we detect no abuse of discretion in the District Court’s order. To the extent that Murphy wishes to challenge his conviction or sentence via an attack on the sufficiency of the indictment or the grandjury proceedings leading to its issuance, the proper way to do so is via a motion to vacate under 28 U.S.C. § 2255. 3 *420 Okereke v. United States, 307 F.3d 117, 120 (3d Cir. 2002). Finally, if Murphy wishes to obtain previously disclosed materials from the District Court or a counter-party, he should make his request with greater specificity and comply with the relevant District Court procedures for requesting record materials.

Thus, as this appeal presents no substantial question, we will summarily affirm. See Murray v. Bledsoe, 650 F.3d 246, 248 (3d Cir. 2011) (per curiam); see also 3d Cir. L.A.R. 27.4; I.O.P. 10.6.
