NEW YORK - Mayor Bill de Blasio on Sunday joined a standing room only crowd in Greenwich Village to discuss their fears about the incoming Trump administration.

They shared ideas on how to limit the President-elect's agenda.

Many expressed their concerns regarding civil rights, marriage equality, and a woman's right to choose.

"We can see the dangers, but we should not go to sleep because we think we can't overcome them because we've overcome them so many times before," De Blasio said.

"I'm afraid of what's going to happen to us and I needed to find a way to participate and push back," said one concerned New Yorker.

"Defending our rights which take a long time to acquire can be lost at the stroke of a pen. It's a part-time job," noted another.

The mayor is scheduled to deliver a similar speech at Cooper Union Monday morning, and will host a town hall in the Bronx Monday night.

You can also see the mayor on his regular "Mondays with the Mayor" segment on "Inside City Hall".

That airs at 7 and 10 p.m.
