UFO Whistleblowers Tell Congress About Government Cover-Ups, Hint at Murders

The federal government goes to great lengths to keep alien spacecraft secret from the public, even killing its own citizens ... at least that's what a whistleblower is strongly suggesting.

The bombshell claim was levied during Wednesday's historic Congressional hearing on UFOs ... with former Air Force intelligence officer David Grusch hinting murder has been a key part of a government conspiracy to hide evidence of extraterrestrials.

Ya gotta see the exchange on Capitol Hill ... Rep. Tim Burchett straight-up asks Grusch if he has any personal accounts of people being murdered over something they've seen in our skies.

The whistleblower's answer is revealing ... "I have to be careful answering that question. I directed people with that knowledge to the appropriate authorities."

Grusch is one of 3 whistleblowers from our military testifying under oath about UFOs and secret government programs allegedly involving extraterrestrial technology. He claims almost 95 percent of UFO sightings go unreported, mainly out of fear of being blackballed, or worse.

The 2 other men being sworn in are Navy fighter pilot commander David Fravor, a witness of the infamous "Tic Tac" UFO sighting, plus former pilot Ryan Graves.

Grusch also testified the U.S. has known about extraterrestrials since at least the 1930s, with the feds covering up a longstanding government program that retrieves and reverse engineers UFOs ... or as he put it, "non-human" spacecraft and pilots.
