Two more women have alleged that Republican presidential candidate Donald Trump made unwanted sexual advances toward them.
A contestant in Trump's television show, "The Apprentice," told reporters Friday that the businessman kissed and grabbed her at a hotel where she had gone to discuss potential jobs. Summer Zervos was a contestant on the show in 2006.

In an article published Friday by The Washington Post, Kristin Anderson said Trump slid his fingers under her skirt and touched her vagina through her underwear in a New York nightclub in the early 1990s.
The 46-year-old resident of Southern California said she pushed his hand away and got up from the couch on which she was sitting. Anderson said she and her companions were "very grossed out" over the incident, which she said lasted less than 30 seconds.
Anderson said she was reluctant to tell her story publicly, but was convinced she should do so after The New York Times, The Palm Beach (Florida) Post and People Magazine published accounts earlier this week of women who said they had been groped by Trump.
These were the latest in a string of recent allegations that Trump groped women or made other sexual advances.
Trump denied all of the allegations at a campaign rally Friday in Greensboro, North Carolina. "I am being viciously attacked with lies and smears," he told supporters. "I have no idea who these women are." He added that the allegations were "100 percent made up."

Earlier, Trump's running mate, Mike Pence, vowed that evidence refuting the claims would be disclosed Friday.
"Before the day is out, there'll be more evidence publicly that calls into question these latest accusations," the Republican vice presidential nominee said on "CBS This Morning."
"Stay tuned. I know there's more information that's going to be coming out that will back his claim that this is all categorically false," Pence added.
In several television interviews Friday morning, Pence criticized the news media for repeating "unsubstantiated" claims against Trump, who has charged that his accusers are part of an international conspiracy to discredit him as the leader of an outsider political movement.
"The Clinton machine is at the center of this power structure," Trump said at a campaign rally Thursday in West Palm Beach, Florida. "Anyone who challenges their control is deemed a sexist, a racist, a xenophobe and morally deformed."
WATCH: Obama, in Cleveland Speech, Says Republicans Should Not Stand by Trump
Democratic candidate Hillary Clinton had no campaign rallies planned Friday, but President Barack Obama campaigned on her behalf at a rally in Cleveland, Ohio. Obama addressed the Trump controversy by referring to remarks made Thursday by first lady Michelle Obama. Without mentioning Trump's name, she said recorded remarks he'd made about women and their bodies were "cruel" and "frightening."
"One of the measures of any society is: How does it treat its women?" the president said. "How does it treat its girls? Are you treating them with respect and dignity and equality? And if you believe that we are better than what we've been hearing, the good news is, as she pointed out yesterday, there's something we can do about it."
Trump has demanded that the Times retract the story it published Wednesday in which two women recounted being groped by him. After Trump threatened to sue, an attorney for the Times said it stood by the story and welcomed the chance to meet Trump in court.
The wife of the Republican presidential candidate, Melania Trump, also threatened to sue a publication over sexual allegations. She said portions of the story published by People Magazine about an alleged sexual assault committed by her husband were "false and completely fictionalized." She demanded a retraction and an apology from the magazine.

The sexual allegations against Trump have prompted numerous Republican officials to distance themselves from the real estate mogul, including House Speaker Paul Ryan, the highest ranking Republican in the U.S.
Ryan said earlier this week he would no longer campaign for Trump or defend him, but stopped short of withdrawing his endorsement of the embattled candidate.
In his first significant public statements since he said he would no longer defend Trump, Ryan accused Clinton and liberals Friday of trying to impose a "gloom and grayness on America."
Ryan told Republican students at the University of Wisconsin, "In the America they want, the driving force is the state. It is a place where government is taken away from the people, and we are ruled by our betters, by a cold and unfeeling bureaucracy that replaces original thinking."
