This was an offhand comment, I took it as a “joke”.
Of course it was a joke, but President Trump also knows how to troll the masses and the media. So much of this drone coverage has been obviously showing just normal air traffic. Why do so many “drones” have a red light on their left and a green light on their right along with flashing strobes in the back? Doesn't that seem like a strangely familiar configuration?
Yes, it was a joke. Never know that from the headline.
