Because I Have To...

If every human on twitter knows you wrote this because you misspelled there, what do you think the mueller team knows about you sir? Keep doing you and we will all be fine. https://t.co/3lBmyPbWUJ

And this is the tweet she's referring to:

This memo totally vindicates “Trump” in probe. But the Russian Witch Hunt goes on and on. Their was no Collusion and there was no Obstruction (the word now used because, after one year of looking endlessly and finding NOTHING, collusion is dead). This is an American disgrace!

We know, Donald. You meant to say "There" was no Collusion... 

David Axelrod weighed in too:

It “totally” did not.  Not even close. The broader question is, why is this man so panicked? And to what lengths will he go to sully or derail a probe he obviously finds threatening? https://t.co/voxSEcaoWk

In my mind, these two tweets, from Wallace and Axelrod, sum up the situation concisely. What does Robert Mueller know and why is POTUS so freaked out about it? Of course, the answer to the second half of the question is contained in the first half. What Mueller knows, or probably knows or will know soon is exactly what the president is so freaked out about. He's not acting like a man with nothing to hide.
