Demagoguery hit the fan. It's never been more obvious. Reputable news sources—not the average British tabloids trying to tell Americans what to do—are rehashing old plays from the playbook: Congress is worried about the president saying things on Twitter. If the president doesn't obey someone he hired and can fire, now that's called "finding a loophole".
The president can say what he wants. The president can do what he wants in the White House without having to find loopholes. That's especially true with the village of cards Obama made with his executive orders that he knew would be so easily blown away by whoever the next guy was to take office. If Obama can create czars with no legal basis, the president should be allowed to talk to a White House staff member without getting permission.
But now, the Russianewsgategate scandal is making its full about turn, though the boomerang isn't quite back in hand yet. The DOJ oversees the FBI; Congress oversees both. Whatever—whatever—Congress says, the FBI and DOJ must do, including answer questions. It seems that they didn't answer questions. Congress is moving for contempt action, which isn't pretty. Though the president kept his peace, now the "directionless" special investigation is so obviously without good purpose that the president feels it's okay to say so.
The funny part is, had Jeff Sessions not caved into the anti-Trump pressure to recuse himself, he would be hit with the contempt action from Congress. But, he played by anti-Trump rules, so, ironically and poetically, Congressional action against a seemingly anti-Trump motive won't hurt him. Grab your popcorn. This will only get more entertaining.
