Three firefighters also suffered minor injuries.
The 3-alarm fire broke out on the 50th floor just after 5:30 p.m. Saturday and was contained less than an hour later, the FDNY says.
President Trump was at the White House and not Trump Tower. He tweeted once the fire was contained.
Fire at Trump Tower is out. Very confined (well built building). Firemen (and women) did a great job. THANK YOU!— Donald J. Trump (@realDonaldTrump) April 7, 2018
Eric Trump, the president's second-oldest son, tweeted that the fire was in a residential apartment at the tower.
