Demonstrators marched through the streets of Fort Collins June 14 as part of nationwide "No Kings" protests against the Trump administration.

At least 1,500 "No Kings" protests nationwide are planned Saturday on the same day President Donald Trump scheduled a large-scale military parade in Washington, D.C. on Flag Day and his 79th birthday.

No Kings protests were held Saturday in nearly 2,000 places across the U.S. The protests were planned on the same day as the military parade in D.C.

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.

"No Kings" protests against the Trump administration are set to take place today in and around New York City as part of nationwide demonstrations. The protests coincide with Saturday's military parade in Washington,

Protests erupted across the U.S. earlier this week, in response to the raids against undocumented immigrants in Los Angeles. At times, the demonstrations took a violent turn as self-driving Waymo taxis were set on fire and concrete was hurled at law enforcement officers.

More than 1.800 anti-Trump "No Kings" protests are expected across the country, with more than 75 in Florida. Here's what to know before you head out.
