The NYPD and FDNY rushed to Trump Tower Tuesday, where the building was being evacuated on a report of a suspicious package in the atrium, sources said.

“We’re staging and units and are standing by,” an FDNY spokesman said, referring further questions to the Secret Service.

A video on Twitter posted by a user named Cielo shows cops waving to people inside the building to get out and crowds running toward the exits.

The incident unfolded shortly before 4:30 p.m. as surrounding streets were packed with holiday crowds

The building is home to president-elect Donald Trump, who was in his Mar-a-Lago resort in Florida on Tuesday.

Team Trump did not immediately respond to a request for comment, and further details were not immediately available.
