Tributes and celebrations poured in Monday as the city remembers civil rights icon Dr. Martin Luther King Jr.

Some of New York's top elected officials gathered in Harlem for the National Action Network's annual MLK Day forum.

Gov. Andrew Cuomo, Mayor Bill de Blasio, and Senators Charles Schumer and Kirsten Gillibrand were among those in attendance.

The governor issued harsh criticisms of President Trump, saying the country needs King's spirit of activism to combat the administration.

"Dr, King's view was there would be a constant crusade and constant force of good and decent people who were outraged at the injustice," Cuomo said. "And they provided the force to bend the moral arc. Our outrage, our activism is more important now than it's ever been. Stand up to what they're doing in Washington because it's vile and repulsive and un-American."

It has been nearly 50 years since King was assassinated.

He would have celebrated his 89th birthday Monday.
