Whether a 28 U.S.C. § 2255 petitioner must affirmatively prove sentencing court relied on residual clause

QUESTIONS PRESENTED FOR REVIEW (1) 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). (2) Whether a district court may rely on current law to evaluate whether a sentencing judge could have relied on the ACCA’s enumerated offense or elements clauses to determine that a defendant’s prior convictions qualified as violent felonies.
