MINNESOTA -- A Minnesota state representative and her husband were shot and killed, and a Minnesota state senator and his wife were shot and wounded in an "act of targeted political violence," Minnesota Gov. Tim Walz said.
A manhunt is now underway for the gunman.
State Rep. Melissa Hortman, a Democrat, and her husband were shot and killed in a what appears to be a "politically-motivated assassination," Walz said.
"She was a formidable public servant," the governor said of his friend. "She is irreplaceable."
State Sen. John Hoffman, a Democrat, and his wife were both shot multiple times and underwent surgery, the governor said.
"We're cautiously optimistic they will survive this assassination attempt," Walz said.
Both were shot at their homes and authorities believe the shooter was impersonating law enforcement, a source familiar with the matter told ABC News.
