Steve Bannon is not likely to remember the year 2018 with great fondness. He has alienated key supporters and is out even at his platform, Breitbart
And there is more. One does not need to be a genius to figure out that Bannon (1) was present or near key events during the Trump campaign that might comprise obstruction of justice, (2) he has a big mouth, and (3) he can be forced to open it.
So Bannon has been subpoenaed by Mueller to testify before a grand jury. That means he has to appear alone — no legal advisors — and sit there as long as it takes, testifying under oath, and not knowing what the prosecutor knows from other witnesses. It is one of the more stressful ways to spend a day, or two or three.
Mueller thinks Bannon will offer useful information one way or another in that setting. Well, we will find out soon enough. And what will the physically and mentally healthy, stable genius do in the White House? Hmmm … pardon Bannon? That might be a political reach given how Trump has so publicly roasted Bannon for the things he said in Mr. Wolff’s very popular book. And pardoning Bannon would remove his ability to take the 5th. It would appear that Trump’s options are limited.
There is one more potential scenario Bannon may have put himself or may now put himself in legal jeopardy. If so, he may come to see that his only potential friend at this stage is Bob Mueller. He might do a deal — if he has evidence that Mueller finds useful enough to do such a deal. If so, we are not likely to find out what that evidence is until after Mueller uses it.
