The targeted shootings of two Minnesota state lawmakers this weekend underscore a grim trend: An increasingly volatile political climate has left state and local officials more exposed than ever to threats and harassment.

Minnesota state Rep. Melissa Hortman and her husband were killed, and state Sen. John Hoffman and his wife were wounded in politically motivated shootings early Saturday, Gov. Tim Walz said. Authorities have also identified a suspect who is still at large.

Vance Luther Boelter, 57, is charged with killing Melissa Hortman, a Minnesota Democrat, and her husband Mark.
