Herman Cain's campaign says detractors who want to "derail the Cain train" are behind the allegation that Cain had a long-running extramarital affair.

A Georgia woman says she and Cain had an affair that lasted 13 years and only ended a few months before he started his White House bid. Ginger White told Fox 5 Atlanta that Cain bought her plane tickets so she could meet him in cities including Palm Springs, Calif.

In its report, the television station said White had Cain's name in her cell phone contacts, and when its reporter sent a text message to the number, he called right back. Cain reportedly said he knew White but said he was trying to help her financially.

White says she came forward because Cain demonized the women who say he sexually harassed them.

Cain, in an interview with CNN as the story was breaking, flatly denied the affair.
