Cain finds accusations ‘disturbing, but false’

>>> good evening. and again here tonight, the campaign of herman cain is in the news. and it's not for his 9-9-9 economic plan or his standing in the polls. because he went before cameras in a wide-ranging news conference and said it just didn't happen. he was talking about the allegations of the woman who came forward, went public, went before cameras yesterday to say she had been sexually harassed by cain years ago. she's one of several accusers. we learned the identity of another one today and she is tonight quoted as having called herman cain a monster. despite his efforts to be final at today's pleads ya event this is likely to continue to haunt the cain campaign for president. we begin tonight with lisa myers . lisa, good evening.

>> reporter: good evening, brian. today herman cain changed his strategy. instead of refusing to answer any more questions, he launched a full-scale assault on one of his accusers. a defiant herman cain says he doesn't remember anything about his latest accuser. not her face or her name.

>> i have never acted inappropriately with anyone, period. the charges and the accusations are absolutely reject. they simply didn't happen. they simply did not happen.

>> reporter: he charged that sharon's claim that he groped her when she came to him with help with a job is part of an effort to derail him and his candidate.

>> and now the democratic machine in america has brought forth a troubled woman to make false accusations , statements, many of which exceed common sense. and they certainly exceed the standards of decency in america.

>> reporter: earlier in the day, the cain campaign even put out the case numbers for a half dozen lawsuits against bialek, as well as two filings for personal bankruptcy. her lawyer defended such attacks yesterday much.

>> she knows by stepping out into the light , she will face public scrutiny.

>> it's not about me. i'm not the one running for president.

>> for her part, bialek is making the media rounds, six interviews in 24 hours , defending her integrity and denying she did this for financial gain.

>> i could have, actually, sold my story, but i didn't. because i wanted -- my whole objective is to tell the truth.

>> would she do an init view for money or write a book in the future?

>> i'd have to think about that. that's so far off the radar right now.

>> reporter: it's a familiar story line , the accuser under a micro scope. debra katz represents victims of sexual harassment.

>> this is hell for the woman who's made this allegation, and her life will never be the same.

>> reporter: late today, another of cain 's accusers said she now intends to speak publicly about incidents with cain . she filed an official complaint with the national restaurant association and received a financial settlement. today one of cain 's opponents waded into the controversy.

>> these are serious allegations.

>> reporter: political analyst charlie cook says if is hurting cain politically.

>> how do you survive three or four direct torpedo hits to the engine room?

>> karen says she wants all four of the women who have made accusations about cain to speak out together. cain says he won't quit the race no matter what, "ain't gonna happen."

>> lisa myers starting us off tonight. thanks.
