Two Republican Jersey Shore-area congressmen, U.S. Reps. Chris Smith and Jeff Van Drew, have called on the military to shoot down the drones. However, Pentagon spokeswoman Sabrina Singh told reporters Wednesday that “our initial assessment here is that these are not drones or activities coming from a foreign entity or adversary.”

Authorities have yet to identify the origin of the unmanned vehicles, which have been spotted hovering in Jersey skies since November.
