Washington, Nov 30 : With the sex allegations piling up, Republican presidential candidate Herman Cain is in the process of reassessing whether to stay in the race for the White House.

A businesswoman Ginger White recently claimed having a 13-year extramarital affair with Cain.

She claimed that she met Cain after a business meeting in the late 1990s and that for over a decade he had flown her to cities around the US where they had sex in upmarket hotels.

In a conference call with campaign staff on Tuesday, Cain once again denied that he had ever had a sexual relationship with White.

“I deny those charges, unequivocally. That being said, obviously, this is cause for reassessment,” the BBC quoted Cain, as saying.

“We have to do an assessment as to whether or not this is going to create too much of a cloud, in some people''s minds, as to whether or not they would be able to support us going forth,” he added.

White''s claims come weeks after it was revealed that two women had been paid compensation by the National Restaurant Association after they complained Cain had sexually harassed them while he was CEO of the organisation.

Earlier this month, a third woman, Sharon Bialek, publicly accused Cain of sexually assaulting her in his car in 1997.

According to the report, since these sexual assault claims his ratings have sliped, while former House Speaker Newt Gingrich’s ratings have surged. (ANI)
