Throughout the day, rumors have been circulating that Assistant Attorney General and overseer of the Mueller probe Rod Rosenstein was about to resign or be fired. The decision has apparently been put off until Thursday.
This is the beginning of an actual constitutional crisis, a conflict within the republic but outside of the Constitution itself. It does not automatically lead to the firing of Mueller, but it makes it much more likely. This is a time for all Americans to be ready to act to preserve freedom as we know it.
