Two additional women have said former Vice President Joe Biden's touches made them feel uncomfortable, reports The New York Times.

Caitlyn Caruso, 22, said Biden rested his hand on her thigh during an event on sexual assault at the University of Nevada at Las Vegas three years ago. Caruso, a sexual assault survivor, said he squirmed in her seat to show her discomfort. Later, Biden hugged her "just a little bit too long," she said.

"It doesn't even really cross your mind that such a person would dare perpetuate harm like that," she told the paper. "These are supposed to be people you can trust."

D. J. Hill, 59, told the Times that Biden put his hand on her shoulder and then started dropping it down her back during a photo-op at a 2012 fundraising event in Minneapolis.

Her husband interrupted with a joke, she said.

"Only [Biden] knows his intent," she said. But norms are changing now, she said, and "if something makes you feel uncomfortable, you have to feel able to say it."

Former Nevada state lawmaker Lucy Flores and Amy Lappos, a former congressional aide to Rep. Jim Himes, D-Conn., were the first two women to allege inappropriate touching.

Biden in a statement Sunday said he has "offered countless handshakes, hugs, expressions of affection, support, and comfort."

"And not once — never — did I believe I acted inappropriately," Biden added. "If it is suggested I did so, I will listen respectfully."
