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

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

Rallies are planned across Long Island and in New York City on Saturday, part of "No Kings" protests in hundreds of American cities scheduled on the same day as a military parade in Washington, D.C., to celebrate the 250th birthday of the U.S. Army.

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Protests are scheduled in Bucks County and nationwide on June 14, with the largest turnout expected in Philadelphia. Here's what to know if you go.
