The House Intelligence Committee was briefed on mysterious drone sightings in the Northeast, with the FBI and Homeland Security deploying technology to investigate. Sightings have spread to Utah and San Diego. Lawmakers, after the briefing, reported no new information beyond what is publicly known. Federal officials suggest the drones could be civilian or law enforcement aircraft, or even mistaken stars, but these explanations are unsatisfactory to some New Jersey officials. Despite public concern, there is no evidence of nefarious activity or foreign involvement. The federal stance is that the situation is not alarming, though this does not reassure all local officials.
