After months of quietly sitting on the sidelines, former Vice President Al Gore is about to hit the campaign trail. Reports surfaced late Tuesday that Gore, who served as Bill Clinton's vice president for eight years, is going to start stumping for Hillary Clinton in the hopes of attracting the millennial vote she still has yet to secure.

The plan is for Gore, best known since leaving office for his climate activism, to attract young voters who are concerned about the environment and leaning towards third-party candidates. The Washington Post reported Gore will make the argument that "voting for an independent presidential candidate could deliver the White House to Republicans in the same way that Ralph Nader's candidacy helped undermine his presidential bid in 2000."

Since Gore and Bill Clinton parted ways, their relationship has been "distant," The Washington Post reported. While Gore did endorse Hillary Clinton back in July, he waited to do so until 49 days after she clinched enough delegates to win the Democratic Party's nomination. Then, despite the fact that he was a superdelegate, Gore skipped the Democratic National Convention, citing other "obligations."

Politico reported that Gore is expected to announce his plans to campaign for the Democratic nominee Wednesday. Becca Stanek
