UFO Senate hearing: Pentagon official 'concerned' about China and Russia's 'advanced tech'

The head of the Pentagon's office tasked with tracking UFOs told lawmakers of "emerging capabilities" and "advanced tech" from potential foreign adversaries — specifically Russia and China — that "are concerning."

But there's no definitive evidence of extraterrestrial technology or alien life, Sean Kirkpatrick, the director of the All-domain Anomaly Resolution Office (AARO), said during Wednesday's Senate meeting of the Armed Services Subcommittee on Emerging Threats and Capabilities. 

"Of the cases that are showing some sort of advanced technical signature … I am concerned about what that nexus is," Kirkpatrick said after he was asked about Russia and China's capabilities to attack and surveil U.S. interests.
