NEW YORK (PIX11) — New York City Mayor Bill de Blasio is calling on Gov. Andrew Cuomo to resign after a former aide to the governor reportedly accused him of groping her.

“He can no longer serve as governor,” de Blasio said at his daily briefing Thursday when asked about the latest allegations against Cuomo. “The latest report…That the governor called an employee in of his, someone who he had power over, called them to a private place, and then sexually assaulted her, is absolutely unacceptable. It is disgusting to me,” the mayor said.

The Times Union on Wednesday reported that the woman, who was not identified, was alone with Cuomo at the governor’s residence when he closed the door, reached under her shirt, and fondled her.

Cuomo later denied the accusation. “I have never done anything like this,” he said Wednesday, calling the details of the report “gut-wrenching.”

The newspaper’s reporting is based on an unidentified source with direct knowledge of the woman’s accusation. The governor had summoned her to the Executive Mansion in Albany, saying he needed help with his cellphone, the newspaper reported.

The three-term governor is also facing sexual harassment allegations from five other women.
