UFO whistleblower David Grusch says President Donald Trump has been fully briefed on secret UFO programs and information about extraterrestrials. Grusch made headlines when he went public saying the Pentagon is operating a secret UFO retrieval program, something the Defense Department has denied. But Grusch's statements prompted other whistleblowers to come forward and lawmakers in Congress to push for more transparency on the subject. Since he first spoke out, multiple hearings on UAPs have been held, and the Pentagon's UAP office has had a shake-up in leadership. Those who have come forward with allegations about government programs have also said the U.S. has retrieved both technology and biological remains from nonhuman intelligence. However, no definitive proof has been provided to back up allegations the government is keeping the existence of aliens a secret. The White House, Pentagon and NASA have all said there is no evidence that UAPs, including sightings that remain unexplained, are extraterrestrial in nature. Grusch suggested that Trump could become an extremely consequential president by revealing information on UAPs and any government programs dedicated to them that might exist.
