The White House says the FBI and the Department of Homeland Security are still investigating the drones spotted in South Jersey and across the Philadelphia region.

White House National Security spokesman John Kirby said there's no evidence that the New Jersey drone sightings are the work for foreign adversaries.

Republican New Jersey Representative Jeff Van Drew announced that the drones flying over his home state are from Iran. The drones, some reportedly the size of small cars, have been described as operating near military installations and critical infrastructure including Picatinny Arsenal and the Verrazzano-Narrows Bridge.
