Minnesota state Representative Melissa Hortman and her husband Mark were killed in a shooting at their home on Saturday morning.

Officials have expressed caution around the nationwide “No Kings” protests after two Minnesota state lawmakers and their spouses were shot early Saturday. One lawmaker and her husband died while the other two survived with severe injuries.

No Kings protests are happening across the United States on Saturday. Here's live coverage of the protests in Minnesota.

The Northeast Minneapolis No Kings protest planned for Saturday has been cancelled amid a shelter-in-place alert.

On the same day Melissa Hortman and her husband were murdered in a "politically-motivated" assassination, more "politically-motivated" violence occurred at peaceful protests across the country.

A man disguised as a police officer shot and killed Minnesota Rep. Melissa Hortman and her husband, and injured Sen. John Hoffman and his wife. The suspect, Vance Boelter, is still at large, and authorities found a manifesto in his car listing other potential targets.

The largely peaceful protests during the "No Kings Day" demonstration in downtown Los Angeles took an intense turn in the afternoon. Police ordered the crowd to disperse at about 4:15 p.m. PDT near Alameda Street and Temple Avenue, according to the Los Angeles Police Department's Central Division.

Thousands marched and rallied peacefully during the No Kings OKC protest on June 14, the same day as the U.S. Army 250th Anniversary military parade.
