House Republicans on Friday announced that their investigation into FBI and Justice Department (DOJ) decisionmaking during the 2016 presidential election has concluded, marking the end of a winding probe launched last fall.

The joint probe — led by the House Oversight and Government Reform and Judiciary committees — sought to investigate what Republicans allege was bias against President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE by the top brass at the two agencies during the heated presidential race.

He did so by notifying the top leaders of the FBI and DOJ — acting Attorney General Matthew Whitaker and FBI Director Christopher Wray — that the probe has concluded, and by releasing a set of key findings and observations from the investigation.

“With the 115th Congress coming to a close, the investigation into decisions made by DOJ and FBI and related interviews conducted by the House Committee on the Judiciary and Committee on Oversight and Government Reform have, at least for the time being, been concluded,” Goodlatte wrote in a letter to Whitaker and Wray.

Goodlatte also released a press release praising the committees’ accomplishments with the probe, including the firings of “multiple high-ranking Justice Department employees.”

In particular, he homed in on the firing of former FBI counterintelligence agent Peter Strzok, who came under immense scrutiny for sending disparaging text messages about Trump during the election. GOP lawmakers seized on the text messages he exchanged with former FBI lawyer Lisa Page — with whom he was having an affair at the time — as evidence of bias against Trump, which he was later fired for in August.

Goodlatte also pointed to the March firing of FBI Deputy Director Andrew McCabe Andrew George McCabeJudge will not dismiss McCabe's case against DOJ Graham: Comey to testify about FBI's Russia probe, Mueller declined invitation Barr criticizes DOJ in speech declaring all agency power 'is invested in the attorney general' MORE, which came after a DOJ watchdog concluded that the No. 2 FBI official had made an unauthorized disclosure to the news media and lacked “candor — including under oath — on multiple occasions."

“Andrew McCabe, Peter Strzok, and others were fired or resigned during the Committees’ investigation, after the investigation and the [inspector general] Report exposed their bias during their investigations,” Goodlatte wrote.

One of Goodlatte’s main takeaways from the probe matched the accusations Republicans have leveled throughout the investigation: The FBI and Justice Department treated Trump unfairly.

“Our 2016 presidential candidates were not treated equally,” Goodlatte wrote, claiming the “DOJ and FBI’s investigation of Secretary Clinton was over before it began.”

He stated that former Secretary of State Hillary Clinton Hillary Diane Rodham ClintonFox News poll: Biden ahead of Trump in Nevada, Pennsylvania and Ohio Trump, Biden court Black business owners in final election sprint The power of incumbency: How Trump is using the Oval Office to win reelection MORE received far more favorable treatment during the probe into her email use than Trump did during the start of the counterintelligence probe into Russian interference.

Strzok had served as the No. 2 on the Clinton probe, and on the beginnings of the special counsel investigation.

“The investigators in both investigations were biased against President Trump. Peter Strzok and Lisa Page exchanged more than 40,000 text messages, including messages such as, ‘Trump is a loathsome human,’ ” Goodlatte wrote.

The Judiciary chairman, who is retiring, pointed to the DOJ inspector general’s report released earlier this year that hammered top FBI officials including Strzok, McCabe and former FBI Director James Comey James Brien ComeySteele Dossier sub-source was subject of FBI counterintelligence probe Judge will not dismiss McCabe's case against DOJ Democrats fear Russia interference could spoil bid to retake Senate MORE.

DOJ Inspector General Michael Horowitz hammered Comey for poor judgment during the election, but found no evidence to show his key decisions in the investigation into Clinton's emails were improperly influenced by political bias.

Horowitz’s report was also highly critical of Strzok’s conduct, stating that his text messages to Page cast a "cloud" on the investigation, but he noted that Strzok was not the sole decisionmaker in any of the investigations they examined. Thus, Horowitz found no evidence of inappropriate influence impacting decisions made in the Clinton probe prior to Comey's announcement that he was closing the case.

Still, despite his criticism, Goodlatte said he still believes “in the mission of the FBI and continue to have great faith in the vast majority of the men and women, who are professional and work day in and day out at the Bureau to combat crime and protect our country.”

Comey as well as former Attorney General Loretta Lynch were among the two final witnesses to interview before the committees’ investigators this month, following more than a dozen others who testified behind closed doors.

Democrats — and even some witnesses — accused House Republicans of holding the private interviews and then selectively leaking to fit their narrative, all in an attempt to undermine Mueller’s probe.

The expected incoming Judiciary chairman, Rep. Jerrold Nadler (D-N.Y.), has publicly stated that he has no plans to continue the investigation — a decision Goodlatte called “unfortunate.”

Goodlatte on Friday urged Whitaker and Wray to review transcripts of interviews the committees conducted as part of the investigations and redact any classified information so they may be made available to the public. He added that the transcripts had been sent over earlier this month and had not been reviewed in a timely manner, saying the “delay” was “very troubling.”

Scrubbing transcripts, however, is a timely process that usually can take months to black out any classified or sensitive data.

The transcript of the committees’ interview with Comey is the only one to have been redacted and published, and the timeline for the release of the other transcripts remains unclear.
