The crime was petty breaking and entering. Not a federal offense was it? The INVESTIGATION was of the coverup, but that crime had not yet been charged, had it? Only AFTER the investigation were those charges brought. See how that works? INVESTIGATION, then CHARGES.
Look, I realize the desperation of you Trumptards on this whole thing. Let it go. Mueller's investigation has its legal mandate and nothing you cry about will reverse that. It's going to proceed and has already uncovered a bunch of shit with more to come. I know it spooks you that each step we've seen so far gets one step closer to the orange-skinned fatass. What are you afraid of? The truth?
