You’ve heard it said of folks who likely are complicit in wrong doing that they “protest too much.”

Donald Trump continues to protest the existence of a special counsel, Robert Mueller. He keeps calling Mueller’s investigation into possible collusion with Russians during the 2016 election a “witch hunt,” which he’s elevated to a “rigged witch hunt.”

Is the president protesting too much? Is he seeking to discredit the investigator as a diversion from the evidence that well might be piling against him?

A politician who is as clean as Trump says he is might just want to keep his trap shut and let the investigation reach a favorable conclusion under its own power.

But that is not happening with this president. He keeps firing off Twitter message, he keeps ad-libbing at press events with statements that — at least to my ear — sound more like a guilty man than an innocent one.
