Meanwhile, "No Kings" protests were scheduled in all 50 states to counter Trump's celebration, in cities like New York, Los Angeles, Philadelphia and Boise.

The parade, honoring the Army’s long-planned 250th anniversary celebration and coinciding with Trump’s 79th birthday, is set to step off from the Lincoln Memorial under the threat of stormy weather in Washington and protests around the country tied to a turbulent week of immigration enforcement that has involved military deployment in Los Angeles.
