A massive crowd is expected to turn out for Saturday’s No Kings protest, last year’s versions of which saw tens of thousands march against the Trump administration and its right-wing, anti-immigrant policies.

In addition to the federal immigration crackdown, organizers of this year’s march are rallying New Yorkers against deep cuts to Medicaid and public education, and the “ongoing consolidation of executive power” by the Trump administration. Concern over the month-old war against the Iranian regime will also be fueling protesters’ ire.

Protesters will gather at Columbus Circle around noon, where they’ll be joined by politicians, including New York State Attorney General Letitia James, noted activists, such as the Rev. Al Sharpton, and movie star Robert De Niro, whose outspoken opposition to the president, whom he has called “an idiot,” provoked Trump to respond last month by calling the actor “low IQ.”

After stepping off from Columbus Circle, the marchers will head east along W. 59th St., then turn south onto Seventh Ave. From there, the protesters, led by faith-based choral and activist groups, will continue heading downtown through Times Square to E. 34th St., singing songs of resistance, before dispersing.

The NYPD declined to share its security plan for managing the huge crowds expected Saturday.

“There will be an adequate security deployment,” an NYPD spokesman told the Daily News in a statement Friday.

While the most recent No Kings protest held amid the frigid cold in January drew what the NYPD estimated as about 2,000 people, an estimated 100,000 people swelled a No Kings march on a warm day last October, while roughly 50,000 people endured rain to march in the city’s first No Kings protest held last June.

“I’m appalled at what’s going on in this country. I can’t believe it,” a 73-year-old protester, who identified herself as Lisa, told the Daily News at the October protest. “I feel like I’m living in Nazi Germany. I feel like I’m in a science-fiction movie — and nobody’s doing anything.”

While 100 people were arrested at the city’s inaugural No Kings protest, the NYPD said no arrests were made in October.

“We had more than 100,000 people across all five boroughs peacefully exercising their First Amendment rights and the NYPD made zero protest-related arrests,” the department posted on X after last fall’s march.
