House Judiciary Republicans are asking a senior FBI official to testify in a transcribed interview, alleging the official has signed off on many "adverse personnel actions" against conservative agents, saying they were being targeted in a "purge."

Their allegations concern Jennifer Leigh Moore, the executive assistant director of the FBI's human resources branch, according to a Sept. 29 letter from Reps. Jim Jordan (R-Ohio), Darrell Issa (R-Calif.), and Mike Johnson (R-La.). Jordan is the ranking member of the House Judiciary Committee.

"This is beyond outrageous," the House Judiciary GOP wrote on Twitter.

The lawmakers said they found out how conservative agents were being targeted while investigating "serious allegations of abuse and misconduct within the senior leadership of the Department of Justice and the Federal Bureau of Investigation."

"During the course of this investigation, we have received protected whistleblower disclosures that the FBI is engaging in a 'purge' of employees with conservative views by revoking their security clearances and indefinitely suspending these employees," the lawmakers wrote.

They added, "Many of the formal notices for these adverse personnel actions have been signed by you," referring to Moore.

What's more, the three lawmakers allege that Moore has "retaliated against at least one whistleblower who has made protected disclosures to Congress."
