The vista from the top of President Trump’s Washington, D.C. hotel is costing taxpayers a pretty penny.

The Trump Organization got a sweet $534,000 discount on the $3 million annual rent it pays to the federal government for the Trump International Hotel five blocks from the White House – just because it keeps the building’s 270-foot-tall tower open to the public.

The discount covered cleaning, security, and utilities costs, according to the General Services Administration, which still owns the former Old Post Office Pavilion, the Washington Post reported Friday.

Trump’s deal to lease the landmark building was set in 2013, three years before he won the presidency — and became the GSA’s ultimate boss.

The unusual credit covered Trump Organization costs for the last three months of 2016, when the hotel was still being renovated, and all of 2017.

With the Washington Monument closed until 2019 for repairs, the tower is the highest observation point in downtown D.C.
