The rallies were among hundreds of "No Kings" protests held throughout the United States, timed to coincide with a military parade celebrating the 250th birthday of the U.S. Army in Washington, D.C. Saturday was also Trump's 79th birthday.

Flag Day commemorates June 14, 1777—the date the Second Continental Congress adopted the American flag. Thirteen alternating red and white stripes. Thirteen white stars in a blue field. A symbol of unity and rebellion.

The 1,800 "No Kings" protests across the country are meant to express frustration over President Trump's actions that organizers say are authoritarian.

Sellers are hawking Army anniversary and "No Kings" T-shirts, hats and other items in a move to cash in on Saturday's military parade and anti-Trump protests.
