National Security Council spokesperson John Kirby spoke Thursday at the White House press briefing about the mysterious drones that have been spotted over New Jersey recently, saying the Department of Homeland Security and the FBI are investigating the sightings.

The public frustration over the lack of answers hit a peak on Wednesday when US Rep. Jeff Van Drew (R, NJ) claimed “highly reliable” sources told him the drones could be coming from an Iranian mothership stationed offshore — a claim the Pentagon quickly denied, without offering any fruther insight.
