Hundreds of protesters gathered in Lower Manhattan early Tuesday evening for a demonstration against President Trump’s escalating immigration crackdown, continuing several days of protests that began more than 2,400 miles away in Los Angeles.

The demonstrators rallied at Foley Square, near a large government building that houses federal immigration offices and the city’s main immigration court, which has become a flashpoint as the Trump administration ramps up the arrest of migrants in courthouses.

Many carried bright yellow signs that said “ICE out of NYC” in Spanish and English.

Andrea Montiel, 31, whose parents are Mexican immigrants, said she showed up at the rally on behalf of family and friends who she said were too worried about their immigration status to demonstrate publicly.

“I think we’re really here just because we hope we can make a difference and show ICE is not welcome,” she said, adding that New York and Los Angeles were connected by their large Hispanic populations. “We’re one community despite the distance.”

As Mr. Trump deployed National Guard troops and Marines to California, Mayor Eric Adams, a Democrat who has largely aligned himself with Mr. Trump’s immigration agenda, said on Tuesday that he did not foresee Mr. Trump sending the military to New York City.

“If there’s ever a need to go beyond the manpower that we have, there’s other ways you do it before you have to come with the look of a military operation,” Mr. Adams said, citing the size and experience of New York City’s police force.
