Mayor Bill de Blasio and Gov. Andrew Cuomo were among the slew of politicians who marched along Eastern Parkway in the West Indian Day Parade on Monday. De Blasio and Cuomo are vowing to take the Trump Administration to court if the president ends protections for undocumented New Yorkers. NY1's Grace Rauh has the story.

It cast a shadow over the festivities along Eastern Parkway: Reports that President Trump is preparing to repeal protections for undocumented immigrants brought to this country as children.

"It doesn't matter if they were born in another country; they were brought up here," de Blasio said to the crowd during the festivities.

De Blasio and Cuomo separately promised to take the Trump Administration to court should the president end the Deferred Action for Childhood Arrivals (DACA) program, which protects young undocumented immigrants from deportation and allows them to work legally in the United States.

"New York will do everything it can, and New York will sue to stop that order from being rescinded," Cuomo said to the media during the parade. "We won't stand for it."

The governor said doing away with the protections could put 40,000 New York State residents at risk of deportation.

The mayor's Republican rival, Staten Island Assemblywoman Nicole Malliotakis, said she too would be opposed to President Trump scrapping the program. But she did not suggest suing over it.

"I don't think we should retroactively strip these individuals of their status right now," said the presumptive Republican nominee for mayor. "Instead, we should be looking to resolve the problem once and for all. Let's create a pathway to citizenship for these individuals."

This parade always draws many politicians, but this year, coming just before the Sept. 12 primary in New York City, meant there were even more out than usual.

"You know why I'm running, right? I'm running because this guy's a fraud," candidate for mayor Bo Dietl said about de Blasio to parade spectators. "He tells people about what he wants to do for them, but yet he hasn't done anything."

De Blasio's Democratic primary opponent, Sal Albanese, was campaigning as well.

"The West Indian community is a major part of New York," the former city councilman said. "I'm here to celebrate with them."

The governor has not endorsed de Blasio's re-election bid. "I'm not voting in this election, so I don't have any primary endorsements at this time," Cuomo said.

A spokeswoman for the mayor said that the de Blasio campaign did not ask for Cuomo's support.
