At least one person was critically injured Saturday in a shooting at a protest against President Donald Trump in Salt Lake City. It came hours after two Democratic lawmakers in Minnesota were shot dead by a gunman.

An estimated 10,000 people were in attendance at the “No Kings” rally that began in Pioneer Park and marched north through the downtown area, the Salt Lake City Police Department said. Gunfire was heard at around 8 p.m., with video posted online showing protesters fleeing in terror.
