A top city official who approved the 2015 sale of a Lower East Side nursing home to a condo developer was fired Friday, only hours after Mayor de Blasio was questioned by federal prosecutors in a probe of the mayor’s fund-raising, according to the Wall Street Journal.

Ricardo Morales, deputy commissioner of the Department of Citywide Administrative Services, OK’d the removal of a deed restriction on Rivington House, allowing it to be sold and turned into a luxury condo.

A DCAS spokeswoman said the leadership change had nothing to do with the mayor’s interview with the US Attorney’s Office and was “in the works for some time.”
