Absolutely not. Furthermore, Mueller's testimony showed he left the vast bulk of the work to the radical, Trump-hating underlings on his team. They conducted a witch hunt, just as the president said, and failed miserably. Wasted time, wasted money, and embarrassed the reputations of the FBI, the DOJ, and the entire concept of a special counsel. Humiliating defeat for the anti-Trump nutters and a shame for our country as a whole.
Mueller's appearance was a nothing burger. BUT moar democraps are now for impeachment than there were before he testified.
It all makes zero difference as the Senate would stop it in it's tracks.
