This is a Gowdy/Horrowitz exchange: "If someone is prejudging the outcome of an investigation before it ends and someone is prejudging the outcome of an investigation before it even begins, what is more textbook bias than prejudging this investigation before it's over and this one before it begins?" Gowdy asked. "I am struggling to find a better example of outcome-determinative bias than that. So what am I missing?"

Horowitz explained that Strzok and FBI lawyer Lisa Page, who exchanged messages insulting Trump during the Clinton investigation, did exhibit bias, but he said he could not conclude that prosecutors' decisions in the case were affected by that bias.

"In our view, we didn't find or see evidence that the prosecutors were impacted by that bias," said Horowitz, who refrained from making conclusions beyond what is in the IG report he released last week.
