WASHINGTON (AP) -- Republican presidential hopeful Herman Cain says he's expecting another accusation soon to be made public -- that he once had an extended extramarital affair with a woman.
In an interview on CNN, Cain said he knows the woman, whom he did not name, and said the accusation is baseless.
He said he does not intend to quit the presidential race as long as he has the support of his wife.
Cain was hit earlier in the month by several accusations that he sexually harassed or groped women more than a decade ago when he was a high-ranking official at the National Restaurant Association.
He has denied any wrongdoing, although his rise in opinion polls has been reversed in the days since the accusations came to light.
