The FBI is investigating after large drones were spotted flying over central New Jersey over the last two weeks. The "cluster of what look to be drones and a possible fixed wing aircraft" have been recently sighted along the Raritan River, the FBI said.

Drones have been spotted in Morris and Somerset Counties, where Donald Trump's Bedminster golf course and the Picatinny Arsenal army base are located.

Mike Walsh, a resident of New Jersey’s Randolph township, told Pix11 he’s seen hundreds of the drones in recent weeks. He said they’re aloft “for hours” at a time and don’t seem to follow any discernible flight path.
