It affects the national security clearances of Mueller’s team. If Pres. Trump doesn’t suspend them until the leaker is prosecuted, he can lose his clearance as well. An apologetic announcement of Mueller’s clearance suspension at SOTU would be a welcome surprise, since Mueller put him in this position by tipping off the CNN crew to a sealed indictment raid, thus denying Stone’s right to a fair and impartial trial.
And Trump’s IT security administrator should switch the clearances off as Trump is speaking, so Mueller goes back to ‘work’ to a computer he can no longer access. Suddenly the Deep State loses ability to communicate with each other securely.
You could call it the Great Trump Redaction Action.
