DY: I think Trump has proven that. He has threatened the USGA with political reprisals over something as petty as them moving a tournament off of one of his golf courses (which is not a national security issue, but would definitely hurt the economy).
His threat to “make the wall 10 feet taller” when he didn’t like something the former Mexican president said about him is something petty and personal that will definitely have national security implications.
Also, he won’t release his tax records because he intentionally undervalues his properties by extreme amounts to avoid paying taxes on them, putting the burden of his wealth on regular citizens.
