New York City is spending big on protecting President-elect Donald Trump and his family, and those costs may top $1 million each day, according to a new report.

CNN reported that figure on Monday, citing three city officials. The high tally is in part explained by the next U.S. president living "in the most densely-populated neighborhood of the nation's biggest city," the report said.

New York City police may assist the Secret Service in protecting Trump, his wife, his children and his grandchildren in the city.

Representatives for the New York City Police Department did not immediately return requests for comment on how much it costs to safeguard the Trump family, and a spokeswoman for City Hall deferred to the NYPD.
