Donald Trump costs New York City $1 million per day

President-elect Donald Trump costs the city of New York $1 million a day in police protection, according to several city officials, CNN reported on Monday — and those costs to his hometown may not drop anytime soon.

As CNN reported, "every president is required to have local law enforcement protection when they return home during their terms," but security for Trump is extra costly because he lives in the heart of the most populous U.S. city.

Trump's children and grandchildren are also receiving official protection, and, with his wife Melania and young son Barron planning on staying in New York at least until the end of the school year, costs will likely remain high.

Trump himself has indicated he might prefer to work from New York City as much as possible, which would be a "substantial undertaking" for city law enforcement, New York City mayor Bill de Blasio said at a press conference Friday.
