Georgia leaders say they're convinced of Davis' innocence

After meeting for nearly two hours with Troy Davis on Friday, two Georgia congressman and the president of the NAACP said they were convinced of his innocence and committed to saving his life.

Congressmen John Lewis and Hank Johnson said they plan to return to Washington to pursue other legal means to resolving Davis' case, which is currently back in the U.S. Supreme Court on appeal. NAACP President Ben Jealous said the case is now a national priority for the organization. Davis was convicted in the 1989 slaying of Savannah police officer Mark MacPhail but his guilt is now in question after several witnesses from his trial have changed their testimony.

Supporters are calling for a new trial for Davis.
