Der Fuhrer will not tolerate..
Nahhhhh...
It's just that Trump insists upon managing his press appearances...
Note that he let the guy back in, later, and let him ask a couple of pointed questions from the Univision agenda...
What you saw was Trump merely demonstrating who was Top Dog in the room, and controlling the pace and sequencing of the questions, not their content...
Frankly, Trump letting that Univision twerp back into the room, on Trump's terms, was a perfect foil and counter to any such charges...
Regardless of whether it was Trump's idea, or that of one of his people, it was frickkin' brilliant, as an antidote to such accusations...
Better luck next time...
