Governors across the U.S. urged calm and vowed no tolerance for violence, while some mobilized the National Guard ahead of marchers gathering in major downtowns and small towns. Through midday, confrontations were isolated.

Atlanta’s 5,000-capacity “No Kings” rally quickly reached its limit, with thousands more demonstrators gathered outside barriers to hear speakers in front of the state Capitol. Huge crowds marched in New York, Denver, Chicago, Houston and Los Angeles, some behind “no kings” banners.

In Minnesota, organizers canceled demonstrations as police worked to track down a suspect in the shootings of two Democratic legislators and their spouses.

Intermittent light rain fell as marchers gathered for the flagship rally in Philadelphia’s Love Park. They shouted “Whose streets? Our streets!” as they marched to the Philadelphia Museum of Art, where they listened to speakers on the steps made famous in the movie “Rocky.”

“So what do you say, Philly?” Democratic U.S. Rep. Jamie Raskin of Maryland shouted to the crowd. “Are you ready to fight back? Do you want a gangster state or do you want free speech in America?”

Trump was in Washington for a military parade marking the Army’s 250th anniversary that coincides with the president’s birthday. There, a massive demonstration toured the city’s streets, led by a banner reading, “Trump must go now.”

In Charlotte, demonstrators trying to march through downtown briefly faced off with police forming a barricade with their bicycles, chanting “let us walk,” while law enforcement in northern Atlanta deployed tear gas to divert several hundred protesters heading toward Interstate 285. A journalist was seen being detained by officers and police helicopters flew above the crowd.

In some places, organizers handed out little American flags while others flew their flags upside down. Mexican flags made an appearance in some demonstrations.

Protests were planned in nearly 2,000 locations across the country, from city blocks and small towns to courthouse steps and community parks, organizers said. The 50501 Movement orchestrating the protests says it picked the “No Kings” name to support democracy and speak out against what they call the authoritarian actions of the Trump administration. The name 50501 stands for 50 states, 50 protests, one movement.

The demonstrations come on the heels of protests that flared up across the country over federal immigration enforcement raids that began last week and Trump ordering the National Guard and Marines to Los Angeles, where protesters blocked a freeway and set cars on fire.

Philadelphia

Thousands gathered in downtown Love Park, with organizers handing out small American flags and people carried protest signs saying things like “fight oligarchy” and “deport the mini-Mussolinis.”

Karen Van Trieste, a 61-year-old nurse who drove up from Maryland, said she grew up in Philadelphia and wanted to be with a large group of people showing her support.

“I just feel like we need to defend our democracy,” she said. She is concerned about the Trump administration’s layoffs of staff at the U.S. Centers for Disease Control and Prevention, the fate of immigrant communities and the Trump administration trying to rule by executive order, she said.

A woman wearing a foam Statue of Liberty crown brought a speaker system and led an anti-Trump sing-along, changing the words “young man” in the song “Y.M.C.A.” to “con man.”

One man in Revolutionary War era garb and a tricorn hat held a sign with a quote often attributed to Thomas Jefferson: “All tyranny needs to gain a foothold is for people of good conscience to remain silent.”

Los Angeles

Thousands gathered in front of City Hall in a boisterous crowd, waving signs and listening to a Native American drum circle and dance performances, before marching through the streets.

Signs included “They fear us, don’t back down California,” “Protesting is not a crime,” “We carry dreams not danger” and “ICE out of LA.” One demonstrator carried a 2-foot-tall (60-centimeter) Trump pinata on a stick, with a crown on his head and sombrero hanging off his back while another hoisted a huge helium-filled orange baby balloon with blond hair styled like Trump’s.

North Carolina

Crowds cheered anti-Trump speakers in Charlotte’s First Ward Park and chanted “we have no kings” before marching behind a “No Kings” banner through the city, chanting “No kings, no crowns, we will not bow down” and “Hey, hey, ho, ho, Donald Trump has got to go.”

Marchers stretched for blocks, led by a group of people holding a giant Mexican flag and bystanders cheering and clapping for protesters along the way.

Jocelyn Abarca, a 21-year-old college student, said the protest was a chance to “speak for what’s right” after mass deportations and the deployment of the National Guard to deal with protesters in Los Angeles last week.

“If we don’t stop it now, it’s just going to keep getting worse,” she said of the Trump administration’s actions.

Minnesota

Before organizers canceled demonstrations in the state, Gov. Tim Walz took to social media to issue a warning after the shootings.

“Out of an abundance of caution my Department of Public Safety is recommending that people do not attend any political rallies today in Minnesota until the suspect is apprehended,” he wrote.

Florida

About a thousand people gathered on the grounds of Florida’s old Capitol in Tallahassee, where protesters chanted, “This is what community looks like,” and carried signs with messages like “one nation under distress” and “dissent is patriotic.”

Organizers of the rally explicitly told the crowd to avoid any conflicts with counterprotesters and to take care not to jaywalk or disrupt traffic.

One march approached the gates of Trump’s Mar-a-Lago resort in Florida, where sheriff’s deputies turned them back.

Urging calm and calling out the National Guard

Governors and city officials vowed to protect the right to protest and to show no tolerance for violence. Some urged calm, while Republican governors in Virginia, Texas, Nebraska and Missouri were mobilizing National Guard troopsto help law enforcement manage demonstrations.

Some governors urged calm and put state police on standby for the weekend.
