A former Democratic nominee for President will step back out on the campaign trail in support of Hillary Clinton.

FOX's Gurnal Scott with more:

Al Gore, who spent eight years as Bill Clinton's Vice President, will target young voters who have been showing interest in third party candidates.

Gore tossed his support behind Clinton in July saying her campaign's focus on the global climate crisis, as part of its platform, won his endorsement.

Gore famously battled George W. Bush for the presidency in 2000 well beyond election day, winning the popular vote, but losing in the electoral college.

The Clinton campaign has pointed to that controversial election as a warning of how important their vote can be.

It's not clear where and when Gore's first appearance on the trail will be.
