Hillary Clinton and aides have recently been pointing to Al Gore's 2000 experience as a warning to young voters who are considering voting for third-party candidates. Al Gore to hit campaign trail for Clinton

Former Vice President Al Gore will soon hit the trail on behalf of Hillary Clinton, with the campaign likely announcing his emergence on Wednesday, two Democrats familiar with the move confirmed to POLITICO.

Clinton and aides have recently been pointing to Gore's 2000 experience as a warning to young voters who are considering voting for third-party candidates. Gore also is a notable spokesman for the issue of climate change — a topic President Barack Obama has also been using to try to energize young voters.


Gore endorsed Clinton in July, as the Democratic National Convention was getting underway, saying the "global climate crisis" inspired him, in part, to throw his support behind the former secretary of state.

"I am not able to attend this year’s Democratic convention, but I will be voting for Hillary Clinton," Gore wrote in the first of a series of three tweets laying out his rationale for endorsing Clinton. "Given her qualifications and experience — and given the significant challenges facing our nation and the world, including, especially, the global climate crisis, I encourage everyone else to do the same."

Campaign officials did not respond to requests for comment.
