New York Governor Andrew Cuomo on Friday reiterated that he will not resign despite earlier calls by top Democrats for him to step aside following damaging allegations of sexual harassment.

The 63-year-old described the growing calls for him to quit as "reckless and dangerous" because they don't know the facts.

"I did not do what has been alleged, period," Cuomo told reporters. "I never harassed anyone, I never assaulted anyone, I never abused anyone."

Cuomo last week denied the allegations and said he would not leave office.

"It's damning to publicize allegations before you know that they are credible … Let the attorney general do her job," he said at the time.

In the latest accusations, the Wall Street Journal reported on Saturday that a former aide, Ana Liss, said Cuomo in 2014 sometimes greeted her with a hug and kisses on both cheeks, called her "sweetheart", kissed her hand and asked her if she had a boyfriend.

The Washington Post reported on Saturday that a former press aide, Karen Hinton, said that in 2000 Cuomo – when he was federal housing secretary under President Bill Clinton – embraced her in a hotel room after a work event.

The new accusations arose after three other women, two of them former aides, had accused Cuomo, 63, of harassing them through unwanted, sexually suggestive comments or inappropriate physical contact, including unsolicited kissing.

The latest development comes a day after New York State Assembly Speaker Carl Heastie authorized the Assembly Judiciary Committee to start an "impeachment investigation" into sexual misconduct allegations against Governor Andrew Cuomo.

Cuomo has vowed to cooperate with authorities inquiring into the matter.
