City leaders are teaming up to take on the Trump administration in the wake of his decision to end DACA. NY1's Lori Chung filed the following report.

With swift reaction, protesters filled the streets, many of them recipients of the Deferred Action for Childhood Arrivals program, or DACA.

"I no longer have any type of protection at this point, and it's just a really scary point," said Flor Reyes, a DACA recipient.

Reyes is one of an estimated 30,000 people in the city affected by President Donald Trump's decision to end DACA wondering what's next.

"It's just really disappointing to see that we trust our government so much in the hopes that they will create a better future for immigrants, and here we are again," Reyes said.

She's not alone. Many speaking out Tuesday say they're afraid they'll lose the ability to work or stay in the country.

"I haven't been to Colombia for 19 years. And going back there certainly frightens me because my family lives here, everybody's here. And now my future's uncertain," said one protester.

Inside City Hall, the mayor and other city leaders pledged support and protection for DACA recipients, part of the group often referred to as Dreamers.

"All Dreamers will have full access to our schools, our hospitals, our city services, our IDNYC," said Mayor Bill de Blasio.

They slammed what some see as the intent behind Trump's decision.

"This is about racism and xenophobia," said City Council Speaker Melissa Mark-Viverito.

Faith leaders like Cardinal Timothy Dolan also offered solidarity.

"To exclude anybody, to caricature anybody, to stereotype anybody, to dismiss anybody is unbiblical, unchristian, un-American and un-New York," Dolan said.

But those directly affected, like Raul Contreras, who works in the Mayor's Office, wait to see what the future holds. 

"Yes, there's a six-month delay, but there's still so much more uncertainty," Contreras said. "It feels like I'm undocumented again, and I'm just trying to prepare."

De Blasio says he'll be working with the mayors of cities all across the country to urge Congress to pass the Dream Act. That's a bill that would provide a legal pathway to citizenship for DACA recipients and other so-called Dreamers.
