TRENTON, N.J. — A large number of mysterious drones have been reported flying over New Jersey and across the eastern U.S., sparking speculation and concern over where they came from and why.

New Jersey Gov. Phil Murphy and U.S. Sen. Andy Kim have both gone out on drone hunts, hoping for answers. The FBI, Homeland Security, state police and other agencies are investigating.

Murphy and law enforcement officials have stressed that the drones don’t appear to be a threat to public safety, but many state and municipal lawmakers have nonetheless called for stricter rules about who can fly the unmanned aircraft — and to be allowed to shoot them out of the sky.

Dozens of witnesses have reported seeing drones statewide since mid-November, including near the Picatinny Arsenal, a military research and manufacturing facility, and over President-elect Donald Trump’s golf course in Bedminster.

Murphy, a Democrat, said Monday that equipment supplied by the federal government has yielded little new info. – The Associated Press
