Republican Rep. Louie Gohmert on Wednesday grilled former special counsel Robert Mueller as he testified before the House Judiciary Committee, accusing him of perpetuating "injustice."

After asking for unanimous consent to enter into the record an article he wrote for Sean Hannity's website, which was titled "Mueller Unmasked," Gohmert went after Mueller on a number of topics.

Echoing talking points from President Donald Trump, the Texas lawmaker took particular issue with former FBI agent Peter Strzok's role in the inquiry. Strzok was removed from the probe after it was discovered he'd sent anti-Trump text messages to an FBI attorney, Lisa Page, with whom he was having an extramarital affair.

Trump and his Republican allies have sought to undermine the credibility of Mueller's probe by pointing to Strzok's involvement.

Strzok was fired from the FBI in August 2018.

Gohmert asked if Mueller knew about Strzok's feelings toward Trump before he was put on the former special counsel's team. Mueller said he did not.

"When I did find out I acted swiftly to have him reassigned elsewhere in the FBI," Mueller said of Strzok in his testimony.

Gohmert, who earlier this month referred to the former special counsel as an "anal opening," also questioned Mueller on his relationship with former FBI Director James Comey.

Mueller and Comey are friends, which the former special counsel acknowledged in his testimony.

Trump's controversial firing of Comey led to allegations of obstruction and was among the 11 possible instances of obstruction outlined by Mueller in his report on the investigation.

"Firing Comey would qualify as an obstructive act if it had the natural and probable effect of interfering with or impeding the investigation … substantial evidence indicates that the catalyst for the President's decision to fire Comey was Comey's unwillingness to publicly state that the President was not personally under investigation," Mueller's report said.

The report added, "The evidence does not establish that the termination of Comey was designed to cover up a conspiracy between the Trump Campaign and Russia."

Toward the end of Gohmert's questioning, he launched an impassioned defense of Trump's repeated attacks on the Russia investigation, which he's often referred to as a "witch hunt."

"If somebody knows they did not conspire with anybody from Russia to affect the election, and they see the big Justice Department with people that hate that person coming after them, and then a special counsel appointed who hires dozen or more people that hate that person, and he knows he's innocent ... What he's doing is not obstructing justice. He is pursuing justice. And the fact that you ran it out two years means you perpetuated injustice," Gohmert said.

Mueller replied, "I take your question."

The former special counsel ultimately determined there was not sufficient evidence to bring conspiracy charges against Trump and his associates in relation to Russian election interference.

But Mueller did not exonerate Trump on the issue of obstruction - a fact he reiterated during Wednesday's House Judiciary Committee hearing.
