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.

The Army pulled off a sweeping affair featuring more than 6,000 soldiers, 50 aircraft, and fireworks to cap the event highlighting its 250th anniversary.

Organizers behind the “No Kings” movement said the protests “come in response to President Trump’s escalating use of military force in American cities and a federal agenda that would strip health care from 16 million people while expanding ICE raids targeting immigrants and protestors,” according to a press release.

President Trump’s military parade in D.C., meant to honor the U.S. Army’s 250th anniversary, triggered massive nationwide protests against authoritarianism under the slogan “No Kings.”

Millions of demonstrators mobilized around the country as a smaller, subdued crowd gathered to witness the display of grandeur and might in the nation’s muggy capital.

Cities and towns across the country are expecting to see “No Kings Day of Defiance” rallies on Saturday as part of a nationwide protest against the Trump administration. Organizers behind the “No Kings” movement are calling the protests a reaction to the large military parade taking place in Washington,

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

Social media users think they’ve spotted Melania Trump’s ‘reaction’ to her husband Donald’s actions at his multi-million dollar military parade. The parade which took place on Saturday (14 June), was to celebrate the 250th anniversary of the US armed forces, but coincidentally also took place on the President’s 79th birthday.

So far, the cities of Birmingham, Mobile, Montgomery, Tuscaloosa, Huntsville, Scottsboro, Fort Payne, Guntersville, Jacksonville, Auburn, Dadeville, Selma, and Dothan have scheduled June 14 protests in Alabama.

More than 1,000 protests are planned across the country in response to an expected military parade in Washington D.C. on June 14.
