In the hours before he makes his planned midday announcement about the future of his presidential campaign, Republican candidate Herman Cain reached out to some of his rivals.

"We have talked to the Cain Camp, but we don't want to characterize the conversations," said Alice Stewart, a spokesman for Rep. Michele Bachmann, R-Minn.

Cain was in a downtown Atlanta hotel Saturday morning, near the site of his campaign headquarters, which he was scheduled to formally open today. He has said he will announce his plans there at an early afternoon appearance.

The Georgia businessman, who has seen his once-meteoric rise in the polls reversed by allegations of sexual misconduct, arrived back in his hometown of Atlanta Friday for his first face-to-face meeting with his wife following his acknowledgement that he made a series of payments to a friend, Ginger White, without her knowledge.

Winter said the two had a 13-year affair. Cain denies wrongdoing, but says the pain that his family has suffered because of the latest charge - which follows allegations of sexual harassment by four other women - may convince him to drop out of the race.

Cain has also acknowledged a big drop-off in campaign contributions.
