Here's a quote from Donald Trump from last March: "You're supposed to be born in this country, so I just don't know how the courts would rule on it. But it's an additional hurdle that he has that no one else seems to have...Someone could look at it very seriously." Someone like Trump apparently.
So it's an issue in March, not an issue in September, and an issue again in January? Trump seems to be quite a flip-flopper.
Stop twisting.
Some times understanding Trump requires one to be quite the contortionist.
