Trump seizes on drone controversy to mock Chris Christie

Christie endorsed Trump in 2016 but was later axed as the head of his transition team. 

Last year, Christie had a short-lived presidential campaign for the 2024 election during which he called Trump a "coward" and a "puppet of Putin," but he dropped out in January.

"I want to promise you this, I'm going to make sure that in no way do I enable Donald Trump to ever be president of the United States again. And that's more important than my own personal ambition," he said when he dropped out. 

Since mid-November, New Jersey residents have been baffled by unexplained sightings of what appear to be drones. 

The sightings have also been reported in other areas of the country, including military installations, prompting lawmakers to demand answers. 

New Jersey Gov. Phil Murphy and law enforcement have said the drones don't appear to be a threat to public safety. 

On Friday, Trump called for the drones to be shot down if there's no reasonable explanation for them. 

"Mystery Drone sightings all over the Country. Can this really be happening without our government's knowledge," he wrote on Truth Social. "I don't think so! Let the public know, and now. Otherwise, shoot them down!!!"
