The No Kings Day of Defiance is expected to be the largest single-day mobilization since President Trump returned to office.

Hundreds of rallies are planned Saturday, the same day President Trump has scheduled a military-style parade through the streets of Washington, D.C.

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.

On June 14, traditionally Flag Day, protestors plan to gather for a “nationwide day of defiance," according to their website.
