New York Gov. Andrew Cuomo on Sunday was accused by a former aide of sexual harassment in a series of tweets. On Monday, his office refuted the accusations.

"There is simply no truth to these claims," Cuomo's press secretary Caitlin Girouard said in a statement.

Cuomo later addressed the accusations when speaking to reporters.

"I heard about the tweet and what it said about comments that I had made. It's not true," he said.

Cuomo added: "Look, I fought for and I believe a woman has the right to come forward and express her opinion and express issues and concerns that she has. But it's just not true."

Lindsey Boylan, 36, who is currently running for political office, alleged that Cuomo sexually harassed her “for years” and claimed those who witnessed his behavior did nothing to stop it.

“I could never anticipate what to expect: would I be grilled on my work (which was very good) or harassed about my looks. Or would it be both in the same conversation? This was the way for years,” she explained in a tweet.

Boyland suggested she wasn’t Cuomo’s only victim.

“Not knowing what to expect what’s the most upsetting part aside from knowing that no one would do a damn thing even when they saw it. No one. And I *know* I am not the only woman,” she posted on Twitter.

Boylan served as a special advisor to Cuomo for economic development from March 2015 to October 2018. She is currently running for Manhattan borough president.

The Associated Press obtained personnel memos from 2018 that indicated Boylan had resigned after complaints against her by several women from Empire State Development’s human resources department.

“Ms. Boyland had behaved in a way towards them that was harassing, belittling, and had yelled and been generally unprofessional,” read a memo from the administration’s ethics officer, according to the AP.
