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

A 33-mile trip from one protest in Annapolis, Md., to the parade grandstand in front of the White House was like a journey between two different countries.

That’s part of why George Atkinson, a former high school government teacher, felt compelled to join a protest in downtown Houston on Saturday. The 89-year-old affixed a sign to his walker that read, “The clothes have no emperor! He’s all hat and no cattle!”

The rallies were among hundreds of "No Kings" protests held throughout the United States, timed to coincide with a military parade celebrating the 250th birthday of the U.S. Army in Washington, D.C. Saturday was also Trump's 79th birthday.

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

The "No Kings" protests were scheduled in Connecticut as early as 9:30 a.m. in Canton and Glastonbury and could last elsewhere until 6 p.m.

An armed man was arrested on Saturday in the area of a "No Kings" rally in West Chester, Pennsylvania, police said.

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.
