Tens of thousands of Americans joined "No Kings" protests across the United States against the Trump administration.

Thousands gathered in Daley Plaza and in suburban events in protests timed to coincide with a military parade in Washington celebrating the Army's 250th anniversary and President Donald Trump's 79th birthday.

Democracy is “in real trouble,” Mark Ruffalo told MSNBC’s Antonio Hylton while attending the “No Kings” rally in New York City Saturday. His words were echoed by Ellen Pompeo, Kerry Washington, Jimmy Kimmel, and many more notable people and celebrities who spoke out in support of the nationwide protests.

We implore everyone not to play into Trump’s hands and fall for his schemes,” the chair of the Washington State Democratic Party said in a statement.

Massive crowds gathered in Cal Anderson Park, aboard a state ferry and at the state Capitol to denounce the hard-line policies of President Donald Trump.

“The most threatening sound to an oligarch is laughter.”

Additional celebrities including Anna Kendrick, Gina Rodriguez-LoCicero and Tessa Thompson were out on Saturday to protest against the Trump administration.

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.
