This is a shot across the Bush’s bow. They’ve started to get vocal in their opposition to Trump. You can bet Trump knows what’s in the docs and it does not put senior Bush in a good light. As another poster noted Bush Jr. signed the law blocking the docs until now, likely thinking dad would be dead by now and nothing would be released. Just a guess. Every card Trump has played so far on matters like this (notwithstanding the obstructionism from establishment Republicans on health care and the wall and immigration), he has come out with a winning hand. Perhaps McCain will fade away soon too (not literally, but that seems inevitable) with the promise of a state funeral and a preserved legacy. You can bet Trump has dirt on him too.
Yes, that’s why Jeb was supposed to be President...
