In a motion for authorization to file a successive 28 U.S.C. section 2255 motion, after defendant's first section 2255 motion was denied, following his convictions of second-degree murder in retaliation against a witness or informant, in violation of 18 U.S.C. sections 1513(a)(1)(B) and 1111(a), and related crimes, the motion is denied where Johnson v. US, 135 S.Ct. 2551 (2015), does not provide relief.
