Another woman is adding her voice to more than nine who have come forward to make sexual assault allegations against Donald Trump in recent weeks.

"Perhaps he will also label me as another nasty woman" said yoga instructor Karena Virginia at a news conference in Manhattan, New York, Thursday (20 October), referencing a slight Trump made toward Hillary Clinton during the final debates the night before.

She recounted how Trump grabbed her breast at the 1998 US Open Tennis Championship. "Hey look at this one, we haven't seen her before. Look at those legs," Virginia alleged Trump told a group of other men before groping her.

When she recoiled against his touch Trump said "'Don't you know who I am?'" she said. "I felt intimidated, and I felt powerless."

Virginia said she lost sleep over come forward because she has "been fearful of bringing unwanted attention to [her] loving family."

At the third and final presidential debates last night (19 October) Trump said that the accusations against him have "been largely debunked" and that Hillary Clinton was behind the number of women who have come out with stories about him.

Earlier this week People Magazine defended a piece by writer Natasha Stoynoff where she alleges Trump sexually assaulted her in 2005 by getting six witnesses to go on the record.

At a campaign rally last week Trump said he was being "viciously attacked" by Stoynoff's accusations and the "lies and smears" of several other women.
