QUESTIONS PRESENTED FOR REVIEW 1.

Whether, to prevail on a successive § 2255 motion, a defendant must, pursuant to 28 U.S.C. § 2244(b)(4), prove by a preponderance of the evidence that his conviction was in violation of a new, retroactive constitutional ruling or does he meet § 2244(b) standard by a showing that his conviction could have so rested.
