A Minnesota man plans to plead not guilty to charges he killed the top Democratic leader in the state House and her husband​ after wounding another lawmaker and his wife​, his attorney said.

Boelter is accused of murdering Rep. Melissa Hortman and her husband and seriously wounding Sen. John Hoffman and his wife.

An attorney for the alleged Minnesota lawmaker assassin wouldn't tell the Star Tribune whether he intends to pursue a mental health defense.
