Well, there is another possibility.
He might not interview trump at all.
Really, he doesn't need it. The evidence he has is very strong. While it would be nice to have trump lying on video, it isn't necessary and his supporters wouldn't believe it anyway.
What muehler needs the most is time, and to keep rosenstein in place. In addition to controlling the scope of the investigation, and approving any indictments, rosenstein also has the power to seal or release any final report. Under the SC rules, rosenstein has to approve any release of information.
If whoever is in that chair says no, we will NEVER find out what is in it, no matter how damming it is.
So this is kind of like the death star rounding the planet to shoot at the moon. It doesn't matter how powerful the gun is if it never gets to fire.
I agree, he has overwhelming evidence and it might just be a ploy to keep Trump occupied and distracted, a way of taking the heat off Rosenstein until they are ready to spring a report on congress and then it would leak to the public. They are gonna dangle something shiny in front of him to get his attention and they got lots, including those who are gonna sing for Mueller. There are lots of leaks, trials, news releases and great investigative journalism to come, none of it will be good for Trump or the GOP.
I see heat is finally focusing where it belongs on Paul Ryan, Trump's chief enabler and defender. He is getting quite a bit of attention and criticism lately, he's holding nunes's chain and is responsible for his actions. I dunno if he's gonna run again, if he does, he might have a problem in november and so will lot's of other republicans. The stink is getting stronger and will stick to the GOP for a long time, all the people with brains and honor left the party, we see them on TV shitting on Trump and the GOP. The GOP has filled itself with racist, losers and fools, the military, security and law enforcement communities are falling away as have the intellectuals, it's increasingly run by grifters. The kinds of candidates and policies the republican base will throw up in the next election cycle primaries will finish them as a national party. Every GOP primary candidate will be a certified fucking loonie within a couple of election cycles, the base will spiral down!
The independents are gonna write the fuckers off in most places after this fiasco. I figure Paul and Mitch might have a "Come to Jesus moment" before summer, no fucking way they want to go into the election with this shit flying around. Who knows, maybe the rats will make history and go down with the ship, but I'll bet a few will jump.
Like I said before, the next elected GOP president will probably be a black person of indeterminate gender, they'll be living on fucking mars by then!
