The parade was the spectacle event Trump had long wanted. It also helped sparked the largest mass opposition to him since his inauguration 145 days earlier.

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

"We are here today in Tacoma saying we will not yield to that darkness in the smallest dimension," said former governor Jay Inslee.

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 parade, honoring the Army’s long-planned 250th anniversary celebration and coinciding with Trump’s 79th birthday, is set to step off from the Lincoln Memorial under the threat of stormy weather in Washington and protests around the country tied to a turbulent week of immigration enforcement that has involved military deployment in Los Angeles.

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.

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.

Thousands are expected to turn out for "No Kings" rallies against President Donald Trump's actions. Here's how organizers and authorities are preparing.

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

A flagship "No Kings" march and rally are planned in Philadelphia, but no events are scheduled to take place in Washington, D.C., where the military parade will take place on Trump's 79th birthday. Organizers of the protests say they want to take attention away from the parade.
