Federal agencies are facing intense pressure Friday to give the public more details on unexplained drone sightings in the New York City metropolitan area that have been going on for weeks over residential neighborhoods as well as restricted sites and critical infrastructure.

Reported drone sightings at night in New Jersey and along the East Coast have sent lawmakers into a panic and spurred demands for an investigation, although federal officials continue to say there is no cause for alarm.

The governor made the announcement on Friday as sightings spread across New York and New Jersey. State and federal authorities said the flying objects posed no threat to the public.
