It is worth suspecting that the FAA's ban of drones across multiple cities and critical infrastructure sites within New York and New jersey in the days following this notification, citing "special security reasons", is part of a false flag operation intended to justify increasingly aggressive drone regulation.
Around the same time, a request was issued by Sen. Gary Peters to expedite a bill that would expand the authority of the Department of Homeland Security and Department of Justice to surveil, track, control and destroy any drone identified as a threat. The rushed push for this bill was objected to by Paul, citing privacy concerns related to the contents of the bill and existing protections for critical infrastructure sites intended to fulfill a similar purpose. https://www.congress.gov/bill/118th-congress/senate-bill/1631/text
In the days leading up to this, there was an unprovoked frenzy in UFO circles and in the media suggesting that foreign adversaries were operating mysterious drones all across the United States. This was later investigated and found to be ordinary, lawful plane and drone operation.
