The “Bull Dog” of the House has a grave warning for Robert Mueller.

Rep. Trey Gowdy (R-SC), known for his tough “prosecutor” persona, sits on the House Intelligence Committee. The Committee on Saturday threatened to hold the FBI and Department of Justice in contempt of Congress for withholding information related to the removal of FBI agent Peter Strzok from Robert Mueller’s Russia investigation.

Rep. Gowdy told Fox News that the Special Counsel faces “integrity” problems after the revelation that Strzok’s removal was due to exchanging anti-Trump text messages with FBI lawyer Lisa Page–with whom Strzok was having an extramarital affair.

“We met with the department of justice … and they have to go through the texts,” Gowdy said.

He then explained the Intelligence Committee’s interest in the Strzok text messages.

“We are not entitled to them, nor do we have an interest in purely personal texts. We are very interested in both anti-Trump and/or pro-Clinton texts. Because, as he made reference to, he was a very important agent in her investigation, also in the ongoing Russian related investigation, perhaps the decision for Comey to change the wording in a statement.”

Gowdy’s remark about “wording in a statement” referred to reports that Strzok encouraged former FBI director James Comey to describe Hillary Clinton’s private email server actions as “extremely careless” rather than “grossly negligent.” The latter term carries legal weight with potential criminal penalties while the former does not.

Gowdy continued: “He is super important and people have a right to know whether agents are biased one way or another. The department is going to go through the texts been going to make them available to us as soon as they can.”

Fox News anchor Martha MacCallum then asked Gowdy if he still has confidence in the Mueller probe, to which the South Carolina lawmaker replied.

“I do, but I got to confess to you, and I understand people who think I’m wrong. I got an email last night from a friend back home saying, ‘Look, Gowdy, let go of the prosecutor stuff.’ I still think that Mueller can produce a product that we all have confidence in, but things like this, make it really difficult — the perception is, is every bit as important as the reality, and if the perception is, you’re employing people who are biased, it makes us really difficult for those of us that would like to defend the integrity of former prosecutors.”

Gowdy’s comments echo the sentiments of many Americans, who question the integrity of agents that have investigated two presidential campaigns, but apparently favor one over the other.

Who knows how many more of them are still in the Mueller’s investigation team. Mueller should dismantle that whole team and excuse himself. Conflict of interest infested cesspool. — Me (@AltmanEager) December 6, 2017

This is proof this is a witch Hunt! How do not know for certainty if Mueller is in conflict of interest!!!!! — Kaye McDonald (@ARRESTBHO) December 3, 2017

President Trump stated it clearly, “ this is a witch hunt”. And how much proof is needed? Wrap it up and end the special council. Let Trump do his job- I’m tired of watching them endulge the lying liberals! He’s our President and deserves our respect. — Love USA (@iloveusa2017) December 7, 2017

This is very sad but it is the inevitable result of blind partisan politics. It is time for Bill & Hillary to be held accountable for their reckless and selfish policies — Jim Long (@jimlong901) December 4, 2017

I have lost all respect for FBI and DOJ

I’m hopeful that you can restore my faith.

Can’t believe all the hate from the tolerant DEMS

If I said any of this about OBUMA or Crooked Hillary when they were in charge and causing chaos I’d be tarred and featherd — mud runner (@Eileen55901) December 3, 2017
