From New York Post (caution: tabloid):

The truth is out there — and late President George H.W. Bush apparently knew it — telling a federal official that an alien made contact with humans at a secretive New Mexico air base in 1964, according to testimony in an explosive new documentary.
Eric Davis, an astrophysicist who was a scientific advisor on the since-disbanded Advanced Aerospace Threat Identification Program, created by Congress in 2007 by late Sen. Harry Reid (D-NV), claimed that Bush confirmed to him in a private conversation details of contact between the military and an alien creature at Holloman Air Force Base in Otero County. Bush told him that three spaceships were seen approaching the base and that an interstellar being emerged from one ship and had a face-to-face encounter with military and CIA officials, Davis said during an interview in “The Age of Disclosure,” a documentary by filmmaker Dan Farah that went live on Amazon Prime on Friday.
