While people are piling on Gowdy - deservedly so - let me play devil's advocate for just a moment. What if Gowdy is saying something between the lines here? I think you might take his "integrity" comment another way. What if Gowdy is saying that he has confidence that Mueller, as a man of integrity, can't look at the evidence that has come to light and realize that his own investigation is based on misconduct of officials that he has known and worked with, including many at the agency of which Mueller was the former head? What if the implication is that a man of "integrity" would close down his own investigation in light of this criminality? That's probably reading too much into Gowdy's remarks, but I think it remains a possibility.
That’s insightful and certainly a possibility.
