The U.S. government is tracking more than 650 cases of UFOs, according to Pentagon officials.
Dr. Sean Kirkpatrick, the director of the All-domain Anomaly Resolution Office compiled a list over 9 months after his team was tasked with investigating UFOs over all domains of U.S. territory.
During the hearing, Kirkpatrick showed a video clip recorded by U.S. military officials during the Iraq war where a metallic sphere can be seen flying above an active warzone.
He says the sightings are concentrated off the East Coast and West Coast of the U.S., in the Middle East, and in the area of the South China Sea.
This was the second hearing in two years after lawmakers began looking for explanations from the Pentagon about the unexplained aerial sightings reported by both the public and military officials.
