More than two dozen protests planned across Southern California on Saturday — part of a national demonstration against President Donald Trump and his policies — will be watched closely by local organizers and officials following unrest this past week in the Los Angeles area.

The “No Kings Day” demonstrations across the country coincide with a military parade the Trump administration is organizing on Flag Day in Washington, D.C., to mark the U.S. Army’s 250th birthday. At more than 1,800 planned anti-Trump demonstrations Saturday, which is also Trump’s birthday, his critics will send a clear message: “In America, we don’t do kings,” according to Indivisible, the progressive organization behind “No Kings Day.”

In a news release, Indivisible organizers said the demonstrations are a way to bring “pro-democracy and pro-worker” allies together to “reject corrupt, authoritarian politics” in the U.S. Protests are planned in communities across Southern California, from Woodland Hills to Pasadena and Anaheim and from Claremont to Riverside and Temecula.

“The majority of us are not OK with what’s going on right now,” Melissa Follstad, a group leader with Indivisible Inland Empire, said Wednesday. “We do not want a king.”

The protests come on the heels of Trump’s deployment of 700 Marines and 2,000 California National Guard troops to Los Angeles to confront protesters who have gathered to condemn Immigration and Customs Enforcement raids across the region. At least 40 people were arrested during anti-ICE protests in Los Angeles Sunday night and into Monday morning, authorities said.

Protests set for Saturday — many of them organized weeks ago — will continue as planned, according to Follstad and other organizers.

“It will be a peaceful protest and people need to get out there and be seen,” Follstad said. “We want our government to be functional. We don’t want our federal employees being fired for no reason. We don’t want our neighbors being picked up by ICE.”

All No Kings events are expected to adhere to a shared commitment to nonviolent protest and community safety, organizers say. Ahead of the Indivisible Inland Empire protest in Rancho Cucamonga, for example, organizers have added more safety marshals, Follstad said, and trained leaders in de-escalation tactics while outfitting them with megaphones, whistles and identification vests.

Indivisible also offers safety training videos to those who register to attend protests, shares information on social media, hands out flyers with safety information at protests and encourages people to take deep breaths and stay calm.

Follstad said organizers also communicate with local law enforcement in advance, and will keep communication open at the event to “stay on the same page as police.” At the end of the protest, organizers work to disperse the crowd, Follstad said.

“We’re going to have every single safety marshal helping people to get going, so that they don’t loiter,” Follstad added. “A lot of times, it is those people who stay after the official event that can potentially get rowdy — and we want to prevent that.”

In Riverside, protesters led by Indivisible Riverside and Riverside Resistance Revival Chorus will gather on Market Street, filling the area with flags, signs and life-size George Washington cardboard cutouts.

“We’re aware of the upcoming protest and will have officers there to help keep everyone safe, whether you’re protesting, passing through, or just nearby,” Riverside police spokesperson, Officer Ryan Railsback, said Wednesday. “We are firmly committed to upholding First Amendment rights, maintaining public order, and protecting people and property.”
