A gunman posing as a police officer killed a senior Democratic state assemblywoman and her husband on Saturday in an apparent "politically motivated assassination," and wounded a second lawmaker and his spouse,

The suspect is accused of fatally shooting Minnesota state Rep. Melissa Hortman and her husband, Mark, at their home. He also shot Minnesota state Sen. John Hoffman and his wife, Yvette, at their home — but they survived the attack.

Minnesota shooting suspect Vance Boelter will face federal charges, including stalking an elected official, murder and shooting at two officials using a firearm, following the shootings of two Democratic lawmakers over the weekend.
