PHILADELPHIA (AP) — Cities large and small were preparing for major demonstrations Saturday across the U.S. against President Donald Trump, as officials urge calm, National Guard troops mobilize and Trump attends a military parade in Washington to mark the Army’s 250th anniversary.

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.

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

In the Greater Boston area, thousands of “No Kings” marches and rallies are taking place, part of major demonstrations planned across the country.

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.

Hundreds protested in Marion against President Trump's policies and actions. Veterans at the protest expressed concern over a military parade and Trump's disregard for constitutional norms. A small group of counter-protestors supporting Trump also attended the rally.
