From NPR.

There is something strange happening in the skies above New Jersey, and no one seems quite sure what to make of it — not the governor, not members of Congress, not the FBI.⁠
⁠
What they know is that starting in mid-November, dozens of drones have been spotted at night flying in at least 10 different counties across the state. What they don’t know is where the drones are coming from, who’s flying them and why. ⁠
⁠
The drones have been spotted above critical infrastructure, according to authorities, including reservoirs, electric transmission lines, rail stations, police departments and military installations. On Thursday, the White House said that there was no indication that the drones have foreign ties, but that the investigation into the sightings is ongoing.⁠
