Apparently, back before Trump became POTUS (?) he agreed to an interview with Gutfeld, even though he was not a fan (and Trump didn't like him, either) and it was supposed to be 10 mins, but turned into 2-1/2 hours. as they clicked/had chemistry and they've been friends ever since.
Awwww....
I remember being irritated by Gutfeld's mocking of Trump back in the day. It's like, WTH are you looking at, you dolt?? I'd have thought if anyone would jump immediately on the Trump train it would be Gutfeld, and yet there he was acting like some swamp rat.
