Some 10,000 people gathered in Salt Lake City for a "No Kings" rally and march as President Donald Trump was overseeing a military parade in Washington, D.C. About an hour into the march, shots were fired.

Arthur Folasa Ah Loo, 39, a Samoan-born fashion designer, was participating in an anti-Trump protest in Salt Lake City on Saturday when he was shot by a man working security, the police said.

Salt Lake City police said​ in a post to social media that the shooting was "possibly associated" with a "No Kings" demonstration.

Five people were shot, three fatally, at the festival in Utah's West Valley City after an altercation broke out between two groups of people.

A fatal shooting in Salt Lake City, a targeted political attack in Minnesota and more; here's what happened during the national day of protest.

A peaceful protest in Salt Lake City turned deadly Saturday night when "Project Runway" alum Arthur Folasa Ah Loo was tragically killed.

A crazed gunman was taken into custody Saturday night after allegedly opening fire on thousands of protesters during a "No Kings" march, which left one person critically injured, Utah police said.

Organizers are accusing the president of putting on the parade as a show of dominance. The protests were peaceful, but came against the backdrop of assassinations in Minnesota.
