CNN reports "Senate Republican Leaders call for Ethics Cmte. Review of Craig Case." ABC News has "Breaking News" on its website stating the same thing.

More details as they unfold on this development.

UPDATE from AP:

Craig's defiant news conference came as Senate Republican leaders in Washington called for an ethics committee review into his involvement in a police sting operation this summer in the airport men's room.

"In the meantime, the leadership is examining other aspects of the case to see if additional action is required," Sen. Mitch McConnell and other top GOP lawmakers said in a written statement.

Earlier, the private group Citizens for Responsibility and Ethics filed a complaint with the ethics committee seeking an investigation into whether Craig violated Senate rules by engaging in disorderly conduct.
