Follow live updates as the military parade in Washington, D.C., kicks off on Trump's birthday. 'No Kings' protests by opponents are planned across the country today.

The DC "No Kings" protest is marching to the White House on Saturday afternoon as President Trump hosts a celebration for the 250th anniversary of the U.S. Army.

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.

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.

Organisers said hundreds of demonstrations were held in a day of defiance to counter a huge military parade hosted by Trump.

Millions are expected to gather in “No Kings” demonstrations in over 1,500 cities on Saturday, the same day the Army will celebrate its 250th anniversary on Trump’s birthday.

The president, on his 79th birthday, sat on a special viewing stand south of the White House to watch the display of American military might.
