Show me where he is Government?
That's right, he's never served in government, much less been president, so all we have for consideration are his words, which are meaningless things he twists as he wishes - truthful hyperbole - in order to sell suckers on the deal he's offering them.
He said "I may" which necessarily implies that he "may not" and that he believes he has discretion in whether to do so or not.
There are lies, there are damned lies, there are statistics, and then there are Trump's truthful hyperboles.
