Manhattan District Attorney Cyrus Vance Jr. on Thursday dropped his objections to having a special prosecutor take over his investigation of Eric Schneiderman — and said he lashed out at Gov. Cuomo in part because he was frustrated at losing control of the probe.

Vance publicly buried the hatchet with Cuomo during a joint news conference at Cuomo’s Manhattan office, two days after Cuomo tapped Nassau District Attorney Madeline Singas to investigate domestic-violence allegations against the ex-attorney general.

“The governor’s office and our office were not in communication as carefully during this period as perhaps we could have been,” Vance said.

“Perhaps I was a little frustrated when the ground rules changed.”

“That said, I think I completely understand the governor’s decision.”

Vance had accused Cuomo of overstepping his bounds by handing the case to Singas, and he appeared uncomfortable during the news conference, repeatedly pursing his lips, fidgeting with a glass of water and looking at a pile of papers when he wasn’t speaking.

Cuomo said Wednesday that it would have been “silly” to let Vance investigate Schneiderman following Cuomo’s March order for a review by the attorney general’s office of a 2015 case in which Vance declined to prosecute movie mogul Harvey Weinstein in the alleged groping of a model.

Schneiderman abruptly announced his resignation Monday, hours after the New Yorker magazine published claims by four women who said Schneiderman assaulted them.

Three women said the incidents came while they were intimately involved with Schneiderman, while the fourth said Schneiderman attacked her when she rebuffed his advances.
