Mueller's mistake

Well, one the them, anyway. This article refers specifically to Mueller not issuing a subpoena for Dump to testify, and that was a significant mistake. I do admit their headline was misleading click bait, but it's a technique that works.

"Overall, we rate Truthdig Left Biased based on story selection and editorial positions that favor the left. We also rate them High for factual reporting due to excellent sourcing and a clean fact check record."
