President Trump was not in New York City this weekend.
The Fire Department of NY commissioner earlier said that firefighters found the occupant of an apartment on the 50th floor and he was transported to a hospital in critical condition.
In addition to the president's 66th-floor penthouse, Trump Tower houses the headquarters of the Trump Organization as well as other residences, offices and stores.
The FDNY earlier tweeted a picture of the building with several windows of the 50th floor ablaze.

"It was a very hard fire, as you can imagine", Nigro said in a briefing outside the building in midtown Manhattan.
Fire sprinklers were not required in New York City highrises when Trump Tower was completed in 1983.
Melania Trump and the couple's son, Barron Trump, are both in Washington, D.C., according to the first lady's spokeswoman, Stephanie Grisham. Over 44 units and about 190 firefighters responded.
The cause of the fire is still unknown. Very confined (well-built building).
The 664-foot Trump Tower has 58 stories, though the top floor is numbered 68. Firemen (and women) did a great job. The fire started in the building's rooftop heating and air conditioning system and left smoke billowing from the roof.
All the injuries then were not life threatening.
