Following accusations of inappropriate behaviour from a third woman, New York Governor Andrew Cuomo is facing a growing fight for his political future on Tuesday.

Already facing heat over accusations the Democrat deliberately underreported COVID-19 deaths in nursing homes, Cuomo formally referred himself for investigation Monday over sexual misconduct allegations by two former aides.

Hours later, Anna Ruch, 33, told the New York Times that the now 63-year-old Cuomo made unwanted advances on her during a wedding in September 2019.

An increasing number of Democrats and Republicans have joined Cuomo’s accusers in calling for the three-term governor to quit.

Sam Abrams, a political science professor at Sarah Lawrence College, said the third accuser “makes it much harder” for Cuomo to stay around.

“He is a fighter and will clear his name if it’s believed to be a misunderstanding,” Abrams said.

“But if he loses the support of the party, and that is happening, he has no future or fourth term.”

Cuomo became a star last spring with his straight-talking yet empathetic coronavirus briefings that contrasted sharply with then-president Donald Trump’s dismissive approach to the pandemic.

Some Democrats even urged him to run for the White House, with many commentators tipping him for a role in President Joe Biden’s administration.

But his stock now appears to have never been lower.

Although Cuomo said Sunday he was “truly sorry” if his conduct had ever been “misinterpreted as an unwanted flirtation,” he denied ever inappropriately touching or propositioning anyone.

Cuomo, who is now loathed by many on the left-wing of the Democratic Party, was slammed for the wording of his apology.

He bowed to pressure for an independent probe into the misconduct claims, which will be led by New York Attorney General Letitia James.

The findings will be disclosed in a public report on a yet unknown date.
