A day after a City Council hearing highlighted the steep costs of police protection around Trump Tower, President-elect Trump told Mayor de Blasio that he’d work with the city on its request for federal reimbursement, city officials said.

The issue has been an acrimonious one ever since the feds offered just $7 million for the NYPD’s round-the-clock security measures through Trump’s inauguration on Jan. 20 — even though city officials argued the true cost was more than $35 million.

The discrepancy has been criticized by city officials and even sparked a Twitter spat between aides to the president-elect and the mayor in late December.

De Blasio spokesman Eric Phillips said the pair only agreed “to work together on the issue,” but spoke of no final resolution.

He said it was Trump who reached out to de Blasio on the matter.

An email to the Trump transition team wasn’t immediately returned.
