Gibbs said the White House would not comment on the former president and husband of the Secretary of State's trip to the regime seeking to free two U.S. journalists being held there as criminals.

"While this solely private mission to secure the release of two Americans is on the ground, we will have no comment," Gibbs said in a statement. "We do not want to jeopardize the success of former President Clinton's mission."
