David Grusch is a United States Air Force veteran and former National Reconnaissance Office employee, who just stated under oath to the House Oversight Committee that the United States military is in possession of alien craft; a craft that includes dead pilots of non-human origin. 

When asked by Nancy Mace, a representative from South Carolina, if his alleged recovered craft came with pilots, he stated, "Biologics came with some of these recoveries, yeah."

Grusch has been called a 'UFO Whistleblower' and claims that when it comes to UFOs and UAPs, "the U.S. government is operating with secrecy—above Congressional oversight."

Despite Grusch's confidence, Department of Defense and NASA spokespeople have stated that they have no knowledge or evidence of such government assets or the existence of extraterrestrial life at all.

As with all claims of paranormal activity and secretive government activities, Grusch's statements are just hearsay for the time being.
