Minnesota Gov. Tim Walz says former state House Speaker Melissa Hortman and her husband were killed in a politically motivated assassination. A second lawmaker and his wife were shot and wounded.

“We must all, in Minnesota and across the country, stand against all forms of political violence,” Walz said at a press conference Saturday. “Those responsible for this will be held accountable.”

The wounded lawmaker was identified as state Sen. John Hoffman, a Democrat, was first elected in 2012. He runs Hoffman Strategic Advisors, a consulting firm. He previously served as vice chair of the Anoka Hennepin School Board, which manages the largest school district in Minnesota.

Hoffman is married and has one daughter. Hortman was the top House Democratic leader in the state Legislature and a former House speaker. She was first elected in 2004.
