I. Whether Mr. Mentor established cause sufficient to overcome the procedural
default of his "ordinary-case" vagueness challenge to his convictions under 18 U.S.C.
§§ 924(c) and (j), because that constitutional claim was "not reasonably available"
prior to Johnson v. United States, 576 U.S. 591 (2015).

II. Whether the Eleventh Circuit misapplies this Court's precedents in Miller-
El v. Cockrell, 537 U.S. 322 (2003) and Buck v. Davis, 1387S. Ct. 759 (2017), by holding
that a certificate of appealability may not issue in the face of adverse circuit
precedent, even where the issues are debatable among jurists of reason and are the
subject of a circuit-split.
