Herman Cain plans Saturday announcement

ROCK HILL, S.C. (AP) — His once-surging presidential campaign all but over, Herman Cain told supporters Friday he would make an announcement Saturday about the future of his Republican White House bid.

Cain, who was heading home Atlanta to talk with his wife, didn't disclose whether he would drop out of the race for the GOP nomination after this week's allegation that he had a 13-year extramarital affair. He told supporters simply to stay tuned.

"Nobody's going to make me make that prematurely," Cain said. "That's all there is to it."

In his remarks in South Carolina, he sent a mixed message as to his intentions. He said he would clarify the next steps of the campaign and assured supporters the affair claim was "garbage." But he also said he needed to consider what he would do with campaign donations already banked if he dropped out of the race.
