The firing of FBI agent Peter Strzok, who led both the bureau’s Hillary Clinton email and Russia probes, shows the special counsel investigation of alleged Trump campaign collusion with Russia is compromised, contends Judicial Watch President Tom Fitton.

Noting that Strzok was the author of the memo that opened the Russia-Trump collusion investigation, the Fox Business Network’s Melissa Francis asked Fitton in an interview Tuesday what the agent’s firing suggests.

“It tells you that the Mueller investigation is compromised. The whole Russia-collusion theory is based on the work that Strzok is instrumental in doing for the FBI,” he said.

Fitton noted the Justice Department inspector general report by Michael Horowitz makes clear that Strzok, as the No. 2 in counter-intelligence, was running the Russia investigation.

“Look, if this was a straight-forward criminal case that was being pursued by a prosecutor, and you had a dirty copy, like you have with Mr. Strzok, the case might be thrown out,” he said.

Fitton said the Justice Department and the FBI need to examine the way the Mueller investigation has been using the evidence Strzok gathered and determine whether or not it has been used to target Trump.

But the Judicial Watch president said that’s “the most charitable analysis.”

“The least charitable analysis is – and the one I think [Trump] ought to follow – is demand, as he tweeting, that it be shut down,” Fitton said.

“There’s no redeeming this investigation, based upon what Strzok was doing, Page was doing, Comey was doing, McCabe was doing, Ohr was doing, with Fusion GPS.”

Fitton was referring to Lisa Page, the former FBI attorney with whom Strzok exchanged virulent anti-Trump texts while they were in an extra-marital relationship; fired FBI director James Comey; fired deputy director Andrew McCabe; and Justice Department official Bruce Ohr.

Ohr’s wife, Nellie Ohr, was working for Fusion GPS at the time the research firm was overseeing the compilation of the anti-Trump “dossier” of unverified political dirt from Russian operatives. The document later was used to obtain a warrant to spy on the Trump campaign during the 2016 election.

President Trump tweeted Tuesday that Strzok “is a fraud, as is the rigged investigation he started.”

FBN’s Francis also asked Fitton about Judicial Watch’s pursuit in court of McCabe emails during the time of the bureau’s investigation of former secretary of state Hillary Clinton’s mishandling of classified information.

Fitton said the emails will confirm that FBI leadership was “interfering on behalf of Hillary Clinton to keep the investigation away from her and not serious enough to warrant indictments and prosecution.”

Friends of Strzok set up a GoFundMe page on Monday for him to cover his legal fees and lost income that had raised more than $350,000 by early Tuesday evening.
