NEW YORK - Mayor Bill de Blasio is calling for an independent investigation after a former aide to Governor Andrew Cuomo accused Cuomo of sexual harassment.

"These allegations are really disturbing," de Blasio told reporters Wednesday during his daily briefing at City Hall. "We as New Yorkers have to take these allegations seriously. This kind of behavior, if it's true is just unacceptable. We've got to get to the truth about this."

De Blasio's comments come a day after Lindsey Boylan, a former aide to Cuomo, detailed what she described as sexual harassment and unwanted attention from Cuomo during her time working in the administration. 

According to Boylan, Cuomo once asked her to play strip poker during a flight from Western New York and in a separate instance, she alleged the governor kissed her on the lips without her permission.

Boylan described the encounters in an online essay. She previously accused Cuomo of harassment in a set of tweets in December but declined to provide details.

Boylan, who is currently running for Manhattan Borough president and unsuccessfully ran for Congress last year, has declined to speak with reporters.

The mayor joins a growing chorus of Democrats who have called the allegations disturbing and called for investigations, including State Senate Majority Leader Andrea Stewart Cousins.

De Blasio, who frequently clashes with Cuomo, said the investigation should be conducted by an independent entity and not "dominated by the governor’s office."

A request for comment from the governor's office was not immediately returned.

Cuomo denied Boylan’s initial accusation in December. Cuomo’s press secretary issued a statement Wednesday saying Boylan’s claims are false.
