Former Sen. Mike Gravel says White House suppressing evidence of ETs
Obama does not want you to know!Gravel says the strongest accounts of alien encounters are from former military officers, such as retired Air Force Capt. Robert Salas, who testified that UFOs temporarily disabled nuclear weapons on his watch.
“The smoking gun of the whole issue, which is when they saw hovering space craft in Wyoming and South Dakota over the ICBM missile silos that the missiles couldn't work,” Gravel says.
Gravel says the media has aided what he sees as a government cover-up by not taking reports of ET encounters seriously.
“What we're faced with here is, in areas of the media, and the government too, an effort to marginalize and ridicule people who have specific knowledge,” he says.
