Protecting President-elect Donald Trump and his family is costing New York City more than $1 million a day, according to a new report.

CNN Money said it confirmed the amount with three city officials knowledgeable about the plans for keeping Trump and his loved ones safe.

And those security costs may not go down. While Trump will move to the White House, reports say that his wife, Melania Trump, and youngest child, Barron, plan to stay at their residence in Trump Tower in midtown Manhattan.

{mosads}John Miller, the New York Police Department’s deputy commissioner of intelligence and counterterrorism, said adding to the cost were Trump’s children. Miller told WCBS that local police must also protect Trump’s adult children and grandchildren, all of whom live in New York City and are also entitled to Secret Service protection.

CNN Money said the Secret Service is primarily responsible for protecting the president-elect, but local law enforcement is charged with assisting the agency. The bill to protect Trump is also particularly costly because the Republican lives in the most densely populated neighborhood of America’s biggest city.

The report said New York City police have set up barricades around Trump Tower, where the president-elect lives, at 56th Street and 5th Avenue, a location directly in the city’s center. A block on 56th street has basically been closed to traffic, altering movement along the major thoroughfare.

Police have also had to close streets to accommodate Trump elsewhere in the city, the report added. On Friday, officials briefly closed the Lincoln Tunnel during rush hour as Trump went to New Jersey.

New York City Mayor Bill de Blasio (D) on Friday asked the federal government to help foot the bill for Trump’s round-the-clock security detail.

“This is a very substantial undertaking,” he told reporters. “We are particularly concerned about overtime costs, and we think it’s a very valid situation to turn to the federal government for the maximum possible reimbursement for those costs.

“We are devoted to making sure this city will keep moving. This is a big challenge and an unprecedented challenge, we know that, but we are committed to making it work.”
