Allies of Latinos and immigrants marched through Manhattan on Sunday chanting “immigrants are welcome here!” as President-elect Donald J. Trump detailed his plans to round up millions of people with criminal convictions living in the United States illegally.

The rally, which began at a Trump hotel overlooking Central Park and passed his namesake Trump Tower on Fifth Avenue, marked the fifth straight day of nationwide protests of the election outcome.

“No hate! No fear! Immigrants are welcome here!” demonstrators shouted, as police including some from the NYPD’s “Disorder Control Unit” kept protesters from the tower.

Julián Gómez, 26, of Jackson Heights, a tenant organizer with the immigrant advocacy group Make the Road, said allies would fight “until the end to make sure all the civil rights are respected.”

“We’re in the streets to say, basically, that we reject Trump’s agenda — racist agenda, xenophobic agenda, anti-immigrant agenda — so that is what we’re accomplishing: to mobilize people not only for the Latino communities but also from other communities that are willing to join us.”

In an interview that aired Sunday on CBS’ “60 Minutes,” Trump said that only once the deportations are finished would he decide how to handle the “terrific people” without rap sheets who are here illegally.

As a candidate, Trump made immigration a centerpiece of his early platform: he accused Mexico of sending mostly rapists and murderers to the United States as immigrants and promised to erect a wall that Mexico would pay for along the border between the two countries.

Sunday’s marchers — numbering well into the thousands — said they hoped to stymie those plans.

Wearing a Hillary Clinton pin, Wilhelmina Perry, 80, of Manhattan’s Upper West Side, a retired social-work teacher at Stony Brook University, vowed “we’re not going to be silent during the Trump administration.”

“We believe in peace, but we’re going to challenge him all the way,” she said. “On every act that he attempts to roll back progressive values, we’re there.”

Barbara Colton, 78, an actress from the Upper West Side, said she had marched with Martin Luther King and has done union work and worked for leftist causes for decades.

She marched slowly along the protest route, a red, white and blue “Proud Nasty Woman” shirt draped over the front of her walker, and a Hillary pin on her jacket.

“Everything I believe in, Trump has flushed down the toilet, and I cannot be silence,” she said. “Silence is complicity and I cannot be silent in the face of evil. You have to open your mouth and speak and protest.”
