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.

Thousands took to the streets in Pittsburgh and across western Pennsylvania, as well as the country, on Saturday as part of a demonstration deemed "No Kings."

The "No Kings Nationwide Day of Defiance" is planned to "reject corrupt, authoritarian politics in the United States," organizers say.

Rallies are expected throughout metro Detroit and dozens of other cities in the state from Midland to Muskegon and Milan to Marquette.

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.

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.

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