What you see is an implanted suggestion by the media saying that Trump was mocking the physical disability of that reporter. He as mocking the reporter all right but he was mocking the flip flopping he was doing about his story. If you watch trumps hands when he speaks he is always using his hands. Now picture what someone does with their hands when they're pretending to be an indecisive person? Imagine someone whining "I don't know"...where's their arms? I'll show you:
Same exact hand positions as Trump. And if they were in motion repeating it a couple of times it would look the same.
So if these people are mocking someone saying "I don't know I don't" who happens to be "handicapped" are they too guilty of mocking a handicapped person? Apparently only if they're Donald Trump and the reporter is a lying leftie.
Wow sorry for the size. But go to google and do an image search for “I don’t know”. Apparently all those people decided to mock a leftist reporter.
