Thibault's departure from the FBI comes after whistleblowers have raised concerns with lawmakers over alleged political bias within the bureau. Senate Judiciary Committee ranking member Sen. Chuck Grassley (R-Iowa) and House Judiciary Committee ranking member Rep. Jim Jordan (R-Ohio) have come forward with allegations from sources within the bureau who said leadership, including Thibault, exerted pressure on subordinates to downplay the Hunter Biden investigation.
Thibault was one of 13 special agents assigned to the Hunter Biden laptop investigation ahead of the 2020 election.
In a July 18 letter sent to FBI Director Christopher Wray and Attorney General Merrick Garland, Grassley named Thibault and detailed "highly credible" whistleblower claims that he did not follow the FBI's strict substantial factual predication guidelines in the course of the Hunter Biden investigation.
"Based on allegations, verified and verifiable derogatory information on Hunter Biden was falsely labeled as disinformation," Grassley wrote. "Accordingly, the allegations provided to my office appear to indicate that there was a scheme in place among certain FBI officials to undermine derogatory information connected to Hunter Biden by falsely suggesting it was disinformation."
After noting that Thibault displayed "a pattern of active public partisanship in his then public social media content," Grassley revealed that in October 2020, one month before the presidential election, Thibault had ordered closed "an avenue of additional derogatory Hunter Biden reporting."
In a separate letter, Jordan disclosed whistleblower allegations that Thibault had pressured his subordinates to pad the number of reported "domestic violent extremism" cases to support the White House's narrative about threats facing the country.
"These whistleblower allegations that the FBI is padding domestic violent extremist data cheapens actual examples of violent extremism," Jordan wrote. "This information also reinforces our concerns — about which we have written to you several times — regarding the FBI's politicization under your leadership," he told FBI Director Wray.
Wray called the allegations against Thibault "deeply troubling" during a Senate Judiciary Committee hearing earlier this month. Thibault was removed from his supervisory role on the Hunter Biden investigation after the whistleblower accusations became public.
