Rep. Raja Krishnamoorthi (D-IL) suggested Wednesday that the unidentified objects spotted flying in New Jersey and New York could pose a national security risk from China. 

The mysterious aerial vehicles, which the FBI is investigating, have been described as resembling small car-sized drones and have been flying over a New Jersey military installation, as well as President-elect Donald Trump’s Bedminster private golf resort. Residents across multiple New Jersey counties have been reporting them in nightly sightings since the middle of November. More recently, people have reported seeing them flying over New York.
