(CNN Money) — New York Mayor Bill de Blasio is asking government officials for $35 million to cover the cost of protecting President-elect Donald Trump until the inauguration.
The amount comes to roughly $500,000 a day.
CNNMoney reported last month that protecting Trump and his family was costing New York City more than $1 million a day. The new figure from de Blasio reflects updated budgeting, a person familiar with the plan told CNN.
At a news conference Monday, de Blasio said he would send letters to President Barack Obama, Congress and administration officials to “formally initiate” a reimbursement process for security costs from Nov. 8, election day, through Jan. 20.
De Blasio also said he spoke with Steven Mnuchin, Trump’s choice for Treasury Secretary, about the request. De Blasio said Mnuchin “fully understood that there was a real important discussion to be had on how we deal with reimbursement issues going forward.”

The cost of protecting Trump won’t necessarily drop significantly once he moves to the White House, since Melania Trump and the couple’s 10-year-old son Barron expect to stay at their Trump Tower home in midtown Manhattan until at least the end of the school year.
Donald Trump has also indicated he plans to return home regularly, especially while his wife and child are still there.
It’s unclear how the city and the federal government will approach security costs in New York after Trump is president. NYPD Commissioner James O’Neill said a post-inaugural plan “hasn’t been firmed up yet.”
At a press conference in November, de Blasio said the city would need help with the security costs, particularly police overtime.
“This is a very substantial undertaking. It will take substantial resources,” he said at the time. “We will begin the conversation with the federal government shortly on reimbursement for the NYPD for some of the costs that we are incurring.”
While primary responsibility for the protection of the president, or president-elect, rests with the Secret Service, local law enforcement is charged with assisting them, particularly in controlling movements of the general public.
Every president is required to have local law enforcement protection when they return home during their tenures, but the cost associated with Trump are particularly expensive: He lives in the most densely-populated neighborhood of the nation’s biggest city.
