The former commander-in-chief appeared on a show broadcast Wednesday to talk about the creation of www.MyCommitment.org, a new Web site intended to cultivate a grassroots movement around citizen service.

Asked what his role might be if his wife were elected president, Bill Clinton answered jokingly, "Whatever she wants me to do."

"I think that if you have been president you have received the greatest gift an American citizen can receive and you should spend the rest of your lifetime giving it back," he added.

"Hillary says, and I think she's probably right about this, that my best use would probably be dealing with difficult, particular foreign issues and help to raise America's standing in the world."

Clinton noted it isn't legal for a president to appoint a member of his or her family to the cabinet, so he couldn't do "any line job."

"But I shouldn't -- there are plenty of talented people in America who can do that and we don't want to confuse policymaking," he said.
