Good question. Plus the fact that they were QUICK to pick up this story. There were all kinds of things Trump said that were much more "controversial"...but they focus on this?
Should be easy to find the guy. And I'll bet Trump is doing that right now.
Oh how sweet it would be if they found him and trump outed him as a dnc plant or even a jebbie plant....
It seems to me that they were going to take that question and however Trump answered it, use it against him. The goal just might be to imply that Trump supporters are crazy (by their terms).
Trump seemed to be looking at the guy with amusement, saying it's his right to speak, and telling him he looked into it. If Trump had him removed or correct him, they would've complained that Trump had him removed because he was denying him free speech.
The elite just cannot get used to Trump listening to what little folk have to say. Is this the same elite who strongly criticized Trump for silencing that crazed invader from Univision?
