Lawmakers are calling for transparency and stricter regulations on drones flying in U.S. airspace after several sightings along the East Coast.Dozens of witnesses have reported seeing the drones — some up to six feet in diameter with lights turned off, flying in multiple states as early as November.White House officials assured people over the weekend that the drones were not a threat or from a foreign country, but did not provide further details on their origin.The response prompted calls from Democrats and Republicans to strengthen federal oversight on drones and airspace and to involve state and local law enforcement in the investigation."They need both to track these drones and to deal with them by working with federal partners to get them out of the sky and to make sure they're not flying over places," Rep. Josh Gottheimer, of New Jersey, said. "I'm not talking about recreational drones at the beach. I'm talking about large drones that are unlicensed or unregistered."Other lawmakers pointed to the possible lapse in inter-agency communication and threat to national security."From the defense department standpoint, they're focused on bombers and cruise missiles," Rep. Mike Waltz, of Florida, said. "It's pointing to gaps in our capabilities and, and our ability to clamp down on what's going on here and we need to get to the bottom of it."The White House says a review of the reported sightings shows some are lawfully manned aircraft, while the Pentagon stated that the aircraft are not U.S. military drones.Drone sightings have so far been reported in New Jersey, New York, Connecticut, Pennsylvania, Massachusetts, Virginia and Ohio.
