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.

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

Law enforcement in Los Angeles have attempted to disperse protesters by using tear gas on Saturday afternoon, aerial footage shows.

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.
