The U.S. Army celebrated its 250th anniversary on Saturday with a massive military parade in Washington, D.C., against a backdrop of political division and protests savaging President Trump.

"It's people's basic right to protest," former Black Panther member Billy X. Jennings said during a day of celebrations at the museum.

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.

"No Kings," a nationwide series of protests scheduled for Saturday, was planned as a counter to the military parade taking place in Washington D.C. on the same day. That parade is being held in honor of the U.S. Army's 250th anniversary and, coincidentally, Mr. Trump's 79th birthday.

Army intelligence analysts are monitoring civilian-made ICE tracking tools, treating them as potential threats, as immigration protests spread nationwide.

The"No Kings" protests are planned to oppose what they see as Trump's power grab. The number of planned events is nearly double that of the April 5 "Hands Off" protest that saw millions of Americans turn out in big and small cities nationwide.

Police in Sonoma and Napa counties are preparing as North Bay protesters join a nationwide wave of No Kings Day rallies.

At least a dozen groups are planning anti-Trump protests in the Los Angeles area Saturday, following eight days of immigration enforcement demonstrations.
