Well, if you can find something in the law that allows Congress to falsely claim that they are a small enterprise employing less than 50 people (and thus to gain financial benefits for themselves) then perhaps Trump can’t do anything. There is a whole lot of “I know nothing, I see nothing” willful ignorance in the government about violations of the law that result in benefit to the swamp dwellers.
Trump needs to “work to rule” Obamacare. If it’s in the law implemented it and harshly as possible. It’s the best way to wake people up. No exemptions. Either that or just gut it but enforcing nothing (but then someone else can undo that)
