Streets filled across the country for 'No Kings' peaceful rallies protesting Trump

Activists and advocacy groups staged a second round of "No Kings" protests across the country on Saturday in response to what they call abuse of power by President Donald Trump and his administration, including his immigration crackdown and the sending of troops into American cities.

Organizers predicted millions would take part, and photos of events from coast to coast -- from Boston to Los Angeles -- showed huge crowds of demonstrators carrying signs protesting the administration's policies such as his mass deportations.

Republicans contended the protests were "hate America" rallies and claimed they're prolonging the federal government shutdown.

There were no reported violent incidents or arrests, according to local police departments.

Roughly 200,000 people showed up for the Washington, D.C. protest, according to organizers.

Scientist and TV personality Bill Nye was among the speakers who took the podium at Washington, D.C., recalling the protests against the Vietnam War.

"We are protesting in the same fashion today. Only today, the stakes are higher. Rather than abandoning a war against an elusive, perhaps sometimes imaginary foe, we are confronting the possible end of our republic," Nye said.

"We are here to tell our lawmakers that what's going on in our government is wrong. They must stop the abuses of this petulant president and his circle of sycophants. No thrones, no crowns, no kings," Nye said to a cheering crowd.

Sen. Adam Schiff, D-Calif., was also among the protesters in Washington, telling ABC News he was struck by one sign that said "silence is compliance."

"We cannot be silent with this increasing militarization of our cities, the abuse of the Justice Department and] the dismantling of science. People need to speak out, and it's wonderful millions around the country are speaking out today," Schiff said in an interview.

"It's wonderful to see so many people out here today to express themselves, to protest, to speak out against the authoritarian lurch of this administration," Schiff added.

Over 100,000 people peacefully participated in the protests across New York City's five boroughs and no arrests were made, according to the New York Police Department.

"The majority of the No Kings protests have dispersed at this time and all traffic closures have been lifted," the NYPD said in a post on X.

The daylong "No Kings" protests follow up on the thousands held in mid-June. They are being run by a coalition of organizations including the American Civil Liberties Union, Indivisible, 50501 and others. Organizers say there are more than 2,600 events planned nationwide -- including major cities such as New York; Washington, D.C.; Chicago and Los Angeles -- and say millions are expected to attend.

They have been "organized by regular people, by volunteers," Deirdre Schifeling, chief political and advocacy officer of the ACLU, told ABC News.

While organizers have not released details on fundraising ahead of the protests, and the coalition has remained relatively decentralized, a few groups have indicated either heavy spending to promote the rallies or planned star power to increase buzz around them.

For instance, Home of the Brave, a political group, said Monday it was spending $1 million to advertise the No Kings protests, including in local and national newspapers.

Celebrities, including Jane Fonda, Kerry Washington, John Legend, Alan Cumming and John Leguizamo, are slated to attend, according to a fundraising email on Thursday from the political action committee Progressive Change Campaign Committee.

"We'll be in the streets for immigrant families under attack and for voters who are being silenced. For communities being terrorized by militarized policing. For families who are about to lose their health insurance. And for every single person whose rights are threatened by this administration's cruelty," the group wrote in the email.

In advance of Saturday’s rallies, law enforcement is actively monitoring social media and the internet, as well as working with local organizers and potential counter-protesters, to get a sense of what might be expected. That vigilance comes as there continues to be heightened concerns about large-scale public gatherings, especially political events.

Republicans have been slamming the protests, claiming that the protests are a reason the Democratic Party does not want to end the ongoing federal government shutdown.

Senate Majority Leader John Thune asserted on Wednesday that Democrats are waiting to solve the funding issues until after Saturday's "No Kings" rallies.

"The truth is -- what Democrats really want is something Republicans can't give them. And that is the approval of their far-left base," Thune said.

Republican leaders have also framed the "No Kings" protests as a series of "Hate America" rallies, framing the upcoming events as meant to criticize America and what it stands for.

"And I encourage you to watch -- we call it the ‘Hate America Rally’ that will happen Saturday," House Speaker Mike Johnson told reporters on Wednesday. "Let's see who shows up for that. I bet you see pro-Hamas supporters. I bet you see Antifa types. I bet you see the Marxists in full display, the people who don't want to stand and defend the foundational truths of this republic."

Johnson did not provide any proof to support his claims that “pro-Hamas supporters” and “Antifa types” will show up. Organizers have said they cannot control who shows up to protests from outside groups and have emphasized wanting to keep protests respectful and nonviolent.

In an interview taped with Fox News’ Maria Bartiromo on Thursday, Trump was asked about the rallies and he shot down that he was a "king."

"They're referring to me as a king. I’m not a king," Trump said.

Some state leaders have also said they are calling up more law enforcement in light of the protests, which supporters of the protests have said may be meant to "suppress" them.

Texas Gov. Greg Abbott, a Republican, wrote on X on Thursday, that he "directed the Dept. of Public Safety and National Guard to surge forces into Austin" ahead of the rallies.

"Texas will NOT tolerate chaos. Anyone destroying property or committing acts of violence will be swiftly arrested,” Abbott wrote.

State Rep. Gene Wu, who chairs the state House’s Democratic caucus, wrote in response, "Sending armed soldiers to suppress peaceful protests is what kings and dictators do -- and Greg Abbott just proved he’s one of them."

Organizers have countered that Republicans in power are responsible for the ongoing shutdown, and have said that Johnson and some other Republicans not saying the name of the protest is telling.

“I think it's really telling that he spent an entire week calling this a 'hate American Rally,' on the attack against this coalition and Americans across the country, and he won't even say the name of the protest," Leah Greenberg, co-executive director of Indivisible, one of the major groups in the "No Kings" coalition, told reporters on a press call on Thursday.

"That's because if you say the name of the protest, 'No Kings,' the entire argument falls apart … there is nothing more American than saying that we don't have kings and exercising our right to peaceful protest," Greenberg said.

When asked if they thought the claims from Republicans would impact participant turnout on Saturday, organizers said they think it could have the opposite effect.

"I think, if anything, it will increase turnout," said Schifeling. "I think Americans can really see through these sad attempts to distract attention from the failure of these Republican Congress people and Republican Trump administration to actually address what most Americans want and need from their government."

Ezra Levin, the co-executive director of Indivisible, told ABC News that he welcomes the publicity, but simultaneously believes Republicans are trying to stop Americans from exercising their First Amendment right.

"I think the Republicans and Trump see that the largest peaceful protest in modern American history is coming together on Saturday to push back against the authoritarian overreach by this regime and its supporters in Congress, and they're looking for ways to message against it ahead of time," he said.
