This must be the most absurd scandal I have seen in 50 years of following politics. The POTUS is being investigated by a special prosecutor for obstructing justice in a case where no crime would have been committed even if he had done what is alleged, and there is no evidence he did squat. In fact, the whole thing was initiated based on a completely bogus document likely produced by the Clinton dirty tricks division.
In short, this is an establishment attempt to rein in Trump and keep him from doing what he was elected to do, dismantle the managerial state and put the people back in charge of their own lives.
Trump can't fire Rosenstein and Mueller fast enough, IMHO. The media will squeal and yelp, but Trump's popularity will increase and congress will have to do its own investigation if it is at all interested in this goofy charade.
This president, any president, is entitled an opportunity to govern. So far, Trump has been denied that opportunity by those with vested interests that are 180 degrees from those of the American taxpayer.
Trump's last chance is at hand. I say he should use the constitutional authority the people gave him, and drain both Rosenstein and Mueller from the swamp.
