Whether Hobbs Act robbery, 18 U.S.C. § 1951(a), is categorically a 'crime of violence' that may serve as a predicate offense under 18 U.S.C. § 924(c)(3)(A)?

QUESTIONS PRESENTED L. Whether Hobbs Act robbery, 18 U.S.C. § 1951(a), is categorically a “crime of violence” that may serve as a predicate offense under 18 U.S.C. § 924(c)(3)(A)? I. If a defendant’s § 924(c) conviction is based on two potential predicates, one of which is a crime of violence and one of which is not, and the jury’s verdict does not indicate which predicate the jury relied on, does the categorical approach or a fact-specific approach apply in determining whether vacatur is required?
