The rise of political violence in the U.S.

Federal authorities posted murder and stalking charges against Vance Boelter Monday, saying he went to the homes of two other state lawmakers early Saturday morning between shooting state Sen. John Hoffman and his wife, and killing DFL House leader Melissa Hortman and her husband. Acting U.S. Attorney Joseph H. Thompson said more than 45 Minnesota state and federal officials were on Boelter’s target list — all of them Democrats.
