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

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.

According to police, 15 people were arrested in connection with the protests, far less than the 94 arrested during anti-Immigration and Customs Enforcement protests Downtown days earlier.

The No Kings events come after days of protests following raids by U.S. Immigration and Customs Enforcement in Los Angeles, and Trump’s subsequent deployment of thousands of National Guard and U.S. Marines troops to “temporarily protect” ICE and other federal personnel, along with federal property.

Thousands of demonstrators marched along Fifth Avenue in New York City on Saturday for a "No Kings" protest.

Thousands of western Massachusetts residents rallied in the streets on Saturday to protest President Donald Trump and his administration’s policies, joining the nationwide “No Kings” movement against actions they called authoritarian.

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

Between activism, election results and protest turnout, the prevailing political winds suggest the backlash to the president is real.
