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.

Thousands of anti-trump protesters are set to rally in "No Kings" protests across America, countering Trump's military parade and opposing his immigration policies.

The demonstrations are gaining additional fuel from protests flaring up over federal immigration enforcement raids.

A flagship "No Kings" march and rally are planned in Philadelphia, but no events are scheduled to take place in Washington, D.C., where the military parade will take place on Trump's 79th birthday. Organizers of the protests say they want to take attention away from the parade.

Anti-Trump protests are planned for Harrisburg, Lancaster, York, Gettysburg and thousands of other places throughout central Pennsylvania and the nation.

The "No Kings Nationwide Day of Defiance" is planned to "reject corrupt, authoritarian politics in the United States," organizers say.
