Some House Democrats are claiming that an FBI whistleblower who testified before Congress under oath lied to lawmakers.

According to a letter obtained by NBC News, Rep. Jerry Nadler (D-N.Y.) and Del. Stacey Plaskett (D-Virgin Islands) have accused Garret O’Boyle of providing false information to the House Judiciary Committee’s Select Subcommittee on the Weaponization of the Federal Government. The letter, addressed to Attorney General Merrick Garland, claims that O’Boyle lied by denying allegations of leaking information to Project Veritas, Newsmax reported.

There are emerging indications that whistleblowing may have resulted in a potential criminal investigation into allegations of lying to Congress.

The letter addressed to Attorney General Merrick Garland highlights O’Boyle’s alleged false statement made during his testimony to Congress. O’Boyle had testified about his concerns regarding the weaponization of FBI investigations, both criminal and intelligence-related, targeting political adversaries of President Joe Biden.

He further claimed that he faced suspension due to expressing apprehensions about a politically motivated investigation, Newsmax noted.

The outlet adds:

But now the FBI is telling House Judiciary and weaponization committees O’Boyle was suspended for leaking details of the FBI’s investigation into Project Veritas’ acquisition of a diary potentially tied to Ashley Biden.

O’Boyle contends he was suspended by the FBI before blowing the whistle publicly, but FBI executive assistant director for human resources Jennifer Moore testified to Congress that O’Boyle is suspected to have shared nonpublic FBI information before he was suspended.

O’Boyle was suspended by the FBI on Sept. 23, according to an attachment on Nadler’s letter to Garland. Project Veritas severed ties with its founder James O’Keefe on Feb. 20.

“There was a level of urgency because of the identity of the individual, and it appeared that he was still accessing case files and information that he wasn’t authorized to have access to and disclosing it because we had seen information obviously in public forums,” Moore testified, NBC News noted.

A spokesman for the former FBI agent denied he lied or leaked any information to any media outlet.

“Democrats are so desperate to distract from Justice Department wrongdoing that they’re willing to embarrass themselves with frivolous attacks on brave FBI whistleblowers,” Weaponization subcommittee spokesperson Russell Dye wrote in a statement to NBC News.

“Garret O’Boyle is a proud veteran and experienced law enforcement officer who has served our nation with honor and distinction. His only crime was speaking out about FBI abuses, and because he exercised his conscience, shameless Democrats now seek to smear his name,” Dye added.
