Mayor Bill de Blasio crony Jona Rechnitz revealed in court Friday that he treated his NYPD pals to an all-expenses-paid trip to Miami to catch a college football championship game — complete with prostitutes as “entertainment.”

Rechnitz said he took then-NYPD Deputy Chiefs James McCarthy and Andrew Capul and now-retired cops Eddie Gardner and Stephen McAllister, who is now the police commissioner in Floral Park, LI, on the jaunt to the BCS National Championship game in 2013. It was the first time the alleged trip has come to light.

The deep-pocketed real estate investor paid for travel, “a suite to watch the game, food, everything,” he told jurors in Manhattan federal court.

“Did you pay for entertainment?” prosecutor Martin Bell asked.

“Yes,” said Rechnitz, who is cooperating with feds in a bid for leniency.

“What was the nature of the entertainment?” Bell continued.

“Prostitutes,” Rechnitz responded.

The 34-year-old de Blasio donor-turned-felon was testifying in the ongoing trial for Norman Seabrook, the once-powerful head of the New York City corrections officers union.

Rechnitz has testified that he helped hedge fund pal Murray Huberfeld bribe Seabrook in exchange for the union investing in the failed fund.

The feds are forcing Rechnitz to divulge all his back-room efforts to corrupt New York — including One Police Plaza and City Hall — in an effort to take the sting out of the defense’s plans to discredit him.

Rechnitz also allegedly footed the bill for top NYPD brass for trips to Las Vegas in 2014 and golf outings in the Dominican Republic in exchange for police favors.

As The Post reported earlier this year, Rechnitz’s pal Jeremy Reichberg allegedly invited a hooker on a trip to Las Vegas involving NYPD brass James Grant and Detective Michael Milici.

On Friday, Rechnitz told his version of that trip from the stand, claiming that he fell asleep on the way to Vegas because he was sick.

“When I woke up, I saw the cops were not fully clothed,” he said.

He closed his eyes so as not to “embarrass them,” he said.
