Sen. Mike Lee's unfounded claims on social media about the slaying of a Minnesota lawmaker have angered his U.S. Senate colleague from the state.

The Republican senator from Utah suggested in social media posts that the killings were the work of “Marxists,” and mocked Minnesota’s Democratic governor. He later issued a more sober condemnation of the violence.

The suspect, 57-year-old Vance Boelter, was arrested late Sunday following a nearly two-day statewide search. The Saturday morning shootings left State Representative Melissa Hortman and her husband, Mark, dead, and wounded State Senator John Hoffman and his wife, Yvette.

The cohosts reacted to the allegedly politically-motivated violence that took place over the weekend and the response by a key official.
