Herman Cain mum on details about meeting with Muslim leaders…UPDATE: Cain apologizes

Update: Cain met with a Virginia-based Muslim group Wednesday afternoon and apologized for his past comments. Details here.

Republican presidential candidate Herman Cain doesn't want to talk about his upcoming meeting with American Muslim leaders.

Cain was in Washington, D.C., Wednesday to support the GOP's "Cut, Cap and Balance" plan to raise the debt ceiling. He answered a series of questions abut the proposal, but went silent when asked what he anticipates for the roundtable discussion he's organizing with Muslims.

"We've gotta move on," Cain said, dismissing the question. The Ticket caught up with him later on the subject of the meeting, and he again declined to comment.

Cain's spokeswoman Ellen Carmichael announced Tuesday that Cain has "reached out to prominent American Muslim leaders and will host a roundtable with them in the next week."

News of the candidate's new effort to reach out to American Muslims comes after a string of comments he made about the religion, including the revelation that he would not allow people of the faith to serve in his cabinet unless they proved their loyalty to the country, and his belief that local governments have the right to ban Muslims from building a place of worship.

Carmichael said the campaign would not unveil "any details" in advance of the meeting.
