Robert De Niro on Thursday called on people to take to the streets to protest President Trump in an upcoming “No Kings Day” on Oct. 18.

“The original No Kings protest was 250 years ago,” De Niro said in a video shared on the Indivisible Project’s Instagram page. “Americans decided they didn’t want to live under the rule of King George III. They declared their independence and fought a bloody war for democracy.”

“We’ve had two and a half centuries of democracy since then, often challenging, sometimes messy, always essential,” the actor continued. “And we fought in two world wars to preserve it. Now we have a would-be king who wants to take it away, King Donald I. F‑‑‑ that!”

“We are rising up again this time, non-violently raising our voices to declare no kings,” De Niro said. “We’re all in this together, indivisible, with liberty and justice for all.”

Across the country, 2,000 “No Kings” protests are scheduled for Oct. 18, according to one of the Indivisible Project’s Facebook accounts.

A frequent critic of Trump, De Niro called him “America’s philistine president” while at the Cannes Film Festival in May.

“In my country, we are fighting like hell for the democracy we once took for granted, and that affects all of us,” De Niro said in a speech after he accepted the Palme d’Or lifetime achievement award.

“That affects all of us here because the arts are democratic,” he continued. “Art is inclusive, it brings people together, like tonight. Art looks for truth. Art embraces diversity. And that’s why art is a threat. That’s why we are a threat to autocrats and fascists.”

In response to the actor’s remarks, Trump fired back at De Niro, calling him a “wacko.”

The initial “No Kings Day” rallies were held across the country on June 14. Protests were held to criticize the Trump administration and coincided with Trump’s 79th birthday and the 250th anniversary parade for the United States Army.
