Speculation is rampant as US lawmakers continue to voice their own opinions about the explosive claims of an illegal, hidden UFO crash retrieval program made public this month by Air Force and intelligence agency veteran David Grusch. Congressman and Marine veteran Mike Gallagher let loose his own theories on the mystery this Tuesday, suggesting that UFOs might be time-traveling craft piloted by humans from the future, as in the 1984 film'The Terminator.' Appearing on ESPN analyst Pat McAfee's sports talk show, the Wisconsin Republican also floated his hypothesis that the unexplained phenomena'could actually be an ancient civilization that's just been hiding here and is suddenly showing itself.' But Rep. Gallagher also brought the conversation back down to Earth, airing his concerns that the airborne mysteries might prove to be breakthrough aerospace technology mastered by a US foreign adversary. 'I'm probably the most interested in is whether it's adversary technology, particularly from China,' said Gallagher, who is also the chair of the House Committee on the Chinese Communist Party. Whether or not we are alone in the universe, the congressman is not alone among his fellow lawmakers in openly airing his UFO concerns.
