You have to admit that Trump handed that moderator her lunch. He owned her.
Well, if you ignore that what he said was completely untrue (he has, in fact, been critical of Zuckerberg and H1Bs), then I guess he did shut her down.
Perhaps other candidates should emulate him. Whenever they are asked “what did you mean when you aid X,” they should all respond, “I didn’t say X.” That’s the kind of accountability I want to see from a President. (/sarc)
