"This was not the enemy," White House press secretary Karoline Leavitt said about New Jersey's mysterious drone sightings.

The White House now says that the drones seen flying over vast swaths of the East Coast were actually just research vessels approved for flight by the Federal Aviation Administration. After those drones took flight and led to concerns among many Americans, some hobbyists also took flight amid the frenzy, the administration says.

A local congressman isn't satisfied with the White House's answers about the mysterious drones seen across New Jersey skies late last year.

Mysterious drones that hovered over New Jersey last month were authorized by the FAA for research and recreation purposes, the White House says.
