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.

Celebrities are joining millions nationwide to protest Donald Trump. On Saturday, June 14, Kerry Washington, Julia Louis-Dreyfus, Jimmy Kimmel, Ayo Edebiri, and more stars attended the “No Kings” demonstrations in various cities.

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.

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.
