He said he would make a "major announcement" on whether hewould press on - at an event still being billed as the grandopening of a new headquarters. It is the latest - and perhaps final - twist in a campaign sagathat has taken the Georgia businessman from unknown longshot tosurprise frontrunner to embattled tabloid subject. He arrived at his suburban Atlanta home on Friday afternoon totalk with his wife of 42 years, Gloria, about whether to press onafter his campaign was rocked by multiple sexual harassmentallegations and this week's claim that he had a 13-year affair. Hedenies wrongdoing. It was their first face-to-face meeting sincethe allegation was made public. Earlier, in a speech in Rock Hill, S.C., Cain wouldn't disclosewhether he would drop out but told supporters to stay tuned. Hesaid he would clarify the next steps of the campaign and assuredbackers the affair claim was "garbage." But he also said heneeded to consider what he would do with campaign donations alreadybanked if he dropped out of the race. "Nobody's going to make me make that prematurely," Cain told acrowd of about 100 people. "That's all there is to it." "My wife and family comes first. I've got to take that intoconsideration," Cain added. "I don't doubt the support that Ihave. Just look at the people who are here."
