Sorry to disappoint you,but only those "liberals "(among which are plenty of conservatives personally repulsed by Trumps moral filth)-who did not understand the enormity of the corruption involved are surprised by Mueller being muzzled.
We know that Trump frantically called at least 11 different officials to try to get the investigation quashed-He tried REPEATEDLY to get investigators fired,just as he himself fired TWO FBI directors for refusing to draw false conclusions to please Trump. None of us are surprised at all that Trumps friends fell on their swords & took legal hits themselves rather than implicate Trump.Trumps a vindictive thug. We know that Putin also wasn't going to lose his Trump card-& Putin has access to ALL of the tapes Jeffrey Epstein made at his disgusting pedo island. That's why Alexander Acosta( the lead prosecutor from the Jeffrey Epstein case) was rewarded by Trump for keeping his name & image intact;without now Secretary of Labor Acostas help in covering up Trumps activities, Trump couldn't have been accepted as a candidate. Do you really dream that major markers being called in & mondo blackmail didn't serve to muzzle the investigation? I'm sure that Mueller was told he & everyone close to him would be fed dioxin (or ruined & fired at best) if he publicly disclosed what he found.
We expected as much-but everyone with an I.Q that exceeds room temperature knows what REALLY happened!
I'm sure that the GOP will be proud of the fact that the biggest traitor our nation has ever known and one who fully intends to be President for Life(or until he defies Putin) -was the means by which Russia seized control of our country!
And I'm sure that when you stand before God & He asks you why you helped support a monster, whose policies will kill millions you will have a REALLY good excuse!
