Utah Gov. Spencer Cox, a rare non-MAGA republican, said the shooting is "deeply troubling...The shooting at tonight’s protest in Salt Lake City is a deeply troubling act of violence and has no place in our public square," Cox wrote on X.

About 30,000 people marched in the No Kings protest against Donald Trump's authoritarian rule between Pioneer Park and the Federal Building before the shooting on South State Street.

Police said the "No Kings" demonstration had been peaceful before the shooting. Hundreds of similar marches and protests rolled out in cities across the country on Saturday to protest Donald Trump by shouting anti-authoritarian slogans and voiced support for protecting democracy and immigrants rights.
