"It was a very hard fire, as you can imagine".
New York Fire Commissioner Daniel Nigro told CNN that no members of the Trump family were present during the fire, and that the building's higher floors do not have fire sprinklers.
The bill was later passed in March 1999 allowing buildings built before that year to not have sprinklers unless there were major renovations. "Firemen (and girls) did a gret job".
Saturday night was not a good sight for New Yorkers as the skies watched the Trump Tower on fire. Around 200 firefighters and emergency medical service workers responded to the fire, he said.
Police identified the man killed as Todd Brassner, 67, a resident of the building's 50th floor.
The person who died lived in the apartment that caught fire.
Streets surrounding the building in Midtown Manhattan have been closed off.
The fire is reportedly on the 50th floor, and several videos on social media show flames billowing out of the windows.
According to ABC 7, New York's ABC affiliate, investigators are working to determine the cause of the fire.
Firefighters reported smoke throughout tower and inspected Trump's residence but did not say if it was damaged. While the fire may be "confined" firefighters will continue to battle the blaze until its determined to be under control. "Members pushed in heroically, they were knocking down the fire and found one occupant of the apartment", the fire department said in a series of tweets.
The four firefighters also suffered smoke inhalation in the blaze, but were expected to recover. He has an office and a home in the building, but he was not in NY on Saturday.
The building houses apartments and office space.
