The New York Mayor is going to send the White House a bill for $35m to cover the cost of the enormous security operation around Trump Tower.

Bill De Blasio has said he is going to write to the Obama administration setting out the daily $400,000 bill from November 8 too January 20 - the day of Donald Trump's inauguration.

The letter reads: "Municipal or state resources should not be subsidizing the President-Elect's decision to maintain multiple permanent residences.

"For all these reasons, we respectfully request that New York City and the state refuse to pay additional security costs associated with maintaining a second residence at Trump Tower once the President-Elect is inaugurated.

"Should the President-Elect choose to maintain two permanent residences for his family, it is reasonable to request he reimburse the city and the state for all additional security expenses from his own significant personal financial resources."

An estimated total security bill of $1m every day means Donald Trump is by far the most expensive US President-elect in history.

Taxpayers are paying out for what could grow to 300 New York police officers to protect the billionaire tycoon.

City officials say they will try for a reimbursement from the federal government but history suggests there is no promise they will recoup the funds.

“The complex challenges and tremendous costs associated with protecting a president and a president’s family in the heart of Manhattan are truly unprecedented,” said Austin Finan, the spokesman for New York mayor Bill de Blasio.

“As such, we will be issuing a full-throated request – with support from congressional leadership and our federal partners – for a complete reimbursement for all costs incurred.”

CNN Money reports, based on three city official sources, that protecting Donald Trump and his family costs $1m a day.

It also reports that the US Secret Service is considering renting a $1.5m-a-year floor, between 13,500 square feet and 15,500 square feet, in Trump Tower to protect the 70-year-old property magnate and his family.

Mr Finan said the $1m per day figure is not accurate, but City Hall has not provided its own estimate.

Wife Melania Trump also reportedly plans to stay living in the Fifth Avenue skyscraper, instead of moving into the White House in January, so 10-year-old son Barron can finish his school year uninterrupted.
