Salt Lake City police are investigating the roles of two self-described "peacekeepers" following a fatal shooting at Saturday's protest that left one person dead and another injured, raising questions about unauthorized security at public demonstrations.

Organizers have planned demonstrations in cities and towns across the country on the same day as President Trump’s parade in Washington to celebrate the Army.

The organizers of this weekend's upcoming "No Kings" protests have issued a video reminding people about the event. The video, released on the No Kings website, reminds those planning to attend of details and calls on people to join the protests.

Thousands of "No Kings Day" protests are set to be held throughout the country on Saturday to protest the Trump administration.

An innocent bystander at a “No Kings” protest in Utah was shot and killed by a “peacekeeper” who was aiming for a different man pointing an AR-15-style rifle toward the crowd, witnesses told Salt Lake City police.

The ‘No Kings’ rally held outside of Highland Park City Hall on June 14 gathered 3,000 for a peaceful protest on Saturday, organizers said.

The anti-Trump protests in Austin remained peaceful, despite a 'credible threat' that forced a brief evacuation of the Texas Capitol complex.
