Democratic candidate to the White House Joe Biden denied Friday accusations, a month ago, of sexual harassment for his previous help in the 1990s, after President Donald Trump hinted that it may be false accusations.

"These (allegations) are incorrect. It never happened," the former US Vice President confirmed in a statement, in response to accusations by Tara Reid, a former employee of his Senate office.

He added that this woman must be heard about sexual assault, but "these stories should be subject to appropriate investigation and scrutiny."

Biden indicated that during his time as a senator in 1993, his former senior aides denied any knowledge of the incident, at a time when Reid said she had complained to them at the time.

Biden's statement also pointed out that news organizations tried to discover the truth of these allegations, and did not find any statements by former employees that "confirm their allegations in any way."

Biden also participated in a morning news program on the "MSNBC" station, in which he said, "This is not true. I say unequivocally that this never happened, and it did not happen ... I do not know why all this was raised after 27 years? I will not ask about her motive. I will not attack her. "

Biden, 77, broke these remarks a month of silence after receiving increasing calls to respond to these allegations, as Reid, 56, said in an audio recording last March that Biden had molested her by hand-to-hand contact, and reported the incident to Washington police Early last month.

Trump confirmed Thursday that he had been accused of "falsely many times," adding to the accusations against his Democratic opponent, "It could be false accusations. I think he should answer them."

As for Democratic Speaker of the House Nancy Pelosi, she expressed this week her "complete respect" of the "Me Two" movement (me too), which encourages women to confront harassment, but added, "There is also a presumption of innocence."

She stated that Biden was "a very sincere person ... who drafted the Anti-Violence Against Women Law" adopted in 1994.
