Whether a 28 U.S.C. § 2255 petitioner should be required to affirmatively prove the sentencing court relied on the residual clause

QUESTION PRESENTED FOR REVIEW Whether, where the record is unclear, a 28 U.S.C. § 2255 petitioner should be required to “affirmatively prove” that the sentencing court relied on the residual clause to determine that his prior offenses were violent felonies, before he is entitled to pursue a claim for relief under Johnson v. United States, 135 S. Ct. 2551 (2015).
