When Jimmy Kimmel asked Hillary Clinton in a late-night TV interview about UFOs, she quickly corrected his terminology. You know, there's a new name," Clinton said. "It's unexplained aerial phenomenon," she said. "UAP. That's the latest nomenclature." Her unusual knowledge about extraterrestrials ... has struck a small but committed cohort of voters. Clinton has vowed that barring any threats to national security, she would open up government files on the subject, a shift from President Barack Obama, who typically dismisses the topic as a joke. Her position has elated UFO enthusiasts, who have declared Clinton the first "E.T. candidate." Stephen Bassett, who lobbies the government on extraterrestrial issues, views a Clinton presidency as a chance to finally get the United States to disclose all it knows about life beyond Earth. Bassett's organization has sent roughly 2.5 million Twitter messages to presidential candidates, elected officials and the media urging a serious discussion of the issue. The movement viewed Clinton's decision to correct Kimmel's use of the term UFO ... as a breakthrough because it "suggested she'd been briefed by someone," Buchman said. In fact, Clinton had been briefed. Her campaign chairman, John D. Podesta ... is not only a well-respected Washington hand, having served as a top adviser to Obama and President Bill Clinton, but is also a crusader for disclosure of government information on unexplained phenomena that could prove the existence of intelligent life outside Earth.
