More than 20 days into phenomenon, Pentagon still has no answers about origins of mysterious NJ drones

More than three weeks after dozens of mysterious drones began popping up in the New Jersey night sky, the public has still been offered no clear insight on what the phenomenon could be. 

Rep. Jeff Van Drew, R-N.J., suggested the swarms of unmanned aerial vehicles could be from an Iranian "mothership." 

The Pentagon shot down his idea.
