Al Gore endorses Hillary Clinton, talks climate change on Florida stop

Al Gore campaigned with Democratic presidential candidate Hillary Clinton for the first time Tuesday preaching climate change. The former vice president was in Florida with Clinton, telling voters that every vote counts. Florida is the state where Gore lost it all in the 2000 race -- by a few hundred votes. Gore hitting the campaign trail with Clinton marks a turning point in the pair's relationship after the two jockeyed for attention from the Oval Office during Bill Clinton's term.
