After a campaign stop in South Carolina, Cain returned to his Atlanta home on Friday afternoon to talk to his wife of 42 years. It was the first face-to-face meeting since a woman claimed to have a 13-year affair with him.
Cain said he would consult with his wife and make an announcement about his political plans.
"My wife and family comes first. I've got to take that into consideration," Cain said at a campaign event. "I don't doubt the support that I have. Just look at the people who are here."
He was once the surprise frontrunner, but Cain's poll numbers and campaign donations have plummeted after multiple sexual harassment allegations and this week's claim that he had an affair.
He denies having the affair, and he has also denied the allegations had sexually harassed women.
