Republican presidential candidate Herman Cain declared he would not quit his bid for the nomination despite ongoing sexual harassment allegations from four women, saying the charges were false and baseless.
"Ain't gonna' happen," Cain said at a press conference he called to address the allegations head on.
Cain denied again that he had ever behaved inappropriately and said the incidents "simply didn't happen."
Earlier Tuesday, Cain's campaign called into question the credibility of the latest woman to accuse him of sexual misconduct.
Cain advisers issued a news release Tuesday outlining what they called Sharon Bialek's "long and troubled history, from the courts to personal finances."
"I don't even know who this woman is," Cain said of Bialek during the press conference. "I tried to remember if I recognized her and I didn't."
His fourth accuser made her claims in front of a television camera Monday afternoon with high profile attorney Gloria Allred at her side.
"He put his hand on my leg and reached for my genitals. He brought my head toward his crotch. I said, 'This isn't what I came here for.' He said, 'You want a job, right?'" Bialek said.
Bialek claims the incident happened in 1997 when she went to Cain for help with finding a job.
She said she told three people at the time about the incident but never filed a workplace complaint because she was not currently employed.
The Cain campaign said the allegations are false.
"When you know that all of this is totally fabricated and you go from anger then you go -- you get disgusted," Cain told Jimmy Kimmel on ABC's "Jimmy Kimmel Live" Monday night.
Until now, Cain has remained silent. But he told Kimmel he's ready to address the issue and move on.
CBN News Chief Political Correspondent David Brody said unless Cain can find a way to do that, these accusations could begin to affect his campaign.
"At some point, Herman Cain is going to really have to put all this behind him. But it's going to be hard because once again we've got another woman coming out this week, and now we're into the second week of this controversy, and it's not going away any time soon," Brody said.
However, Cain said he's in it to win it, refusing to be discouraged.
"For two weeks, all you heard was Perry, Romney, Romney, Perry. I thought it was a song and -- the media was trying to tell the American people who the two candidates was going to be," Cain said.
"But let me tell you what I have learned as a result and as indicated by the success that we've had," he added. "The voice of the people is stronger than the voice of the media, and the people are going to elect the nominee and the next president of the United States."
"They're not going to be easily swayed by just what the media hype is," he said.
The results of a new ABC News/Washington Post poll supports Cain's theory. It was released just before this latest accusation.
But it shows many Republican voters aren't buying the claims that have been made against him.
Twenty-two percent of the respondents said Herman Cain is the most honest and trustworthy of the candidates.
The next highest on the honesty question was Mitt Romney at 17 percent.
Meanwhile, one of the two original accusers was identified publicly as Karen Kraushaar. Kraushaar is now a spokeswoman in the Treasury Department's office of inspector general for tax administration.
Cain said he recalled her accusation, the only charge every formally filed, but the allegations were "found to be baseless."
