Sen. Tina Smith (D-MN) confronted Sen. Mike Lee (R-UT) on Monday evening after his controversial online posts about the political assassination and attempted murder of Minnesota state lawmakers.

Lee downplayed and joked about what authorities say were politically motivated shootings over the weekend by Vance Boelter, who was charged Monday with a half-dozen federal crimes, including murder and stalking. He allegedly killed Democratic Minnesota House Speaker Melissa Hortman and her husband and shot Democratic state Sen. John Hoffman and his wife, who remain hospitalized.
