Carl Pratt, federal prisoner # 11902-035, appeals the district court’s denial of his motion for release pending the disposition of his 28 U.S.C. § 2255 motion. Release pending disposition of a § 2255 motion will be granted only if (1) the petitioner has raised a substantial constitutional claim upon which he has a high probability of success, and (2) extraordinary or exceptional circumstances exist which make the grant of bail necessary to make the habeas remedy effective. Calley v. Callaway, 496 F.2d 701, 702 (5th Cir. 1974). Regardless of the merits of Pratt’s claims, upon which the district court has not yet ruled, Pratt has not pointed to any “extraordinary or exceptional circumstances” which necessitate his release to make the post-conviction remedy effective. The district court did not err by denying Pratt’s motion for release.

AFFIRMED.
