When Minnesota Attorney General Keith Ellison, a Bernie Sanders supporter, defended so-called Bernie Bros on Twitter and asked for examples of the Vermont senator’s backers “being bad,” U.S. Rep.

Scalise, a Louisiana congressman and the House Republican minority whip, was one of several people injured during a 2017 shooting at a practice for the annual congressional baseball game in Alexandria, Va.
