The United States Secret Service, vested with protecting every president and their family, are reportedly in talks to rent space in the luxurious Trump Tower.

New York's police department are also part of the operation and are looking at renting a combined two floors and station as many as 250 agents and police in the building, sources told the New York Post.

The tower is owned by the Trump Organisation, and President-elect Donald Trump is the company's chairman and president until his inauguration on 20 January 2017.

The 58-storey building is offering 3,000 to 5,000-square-feet spaces for $105 per square foot. About 26 floors of the building are reserved for office space and the rest are luxury condos. Space in one condo goes for $3,132 per square foot. If the agencies rent two floors of office space they will be paying about $1.05m per annum.

Unlike the expenses to protect past presidents, this cash will go directly to a company controlled by Trump's immediate family. Management of the company will be passed to Trump's children Donald Trump Jr, Ivanka Trump, and Eric Trump after the inauguration.

The beefed-up security will protect Trump when he is in New York and watch over the president-elect's wife Melania and 10-year-old son Barron who are said to be staying in the building until the spring of 2017.

The Trump Campaign took heat over the summer after the amount of rent it was paying in the building jumped from $35,457 per month up to April to $169,758 in August after a flood of campaign donations poured in. The campaign defended the extra expenses saying that it had added two more floors of offices after initially occupying just one floor.

Whenever a president travels on vacation or holiday it is customary for the Secret Service to rent space and provide protection. While George HW Bush was president it cost about $2m of tax payers' funds every year to have the US Coast Guard patrol the waters off his estate on Walker's Point in Maine.
