The latest case in point: The FBI has been accused of obstructing congressional oversight of its investigation into the pipe bombs discovered at the headquarters of the Democrat National Committee and Republican National Committee on January 6, 2021.

House Republicans on the Judiciary Committee reiterated their demand on Wednesday for a thorough briefing on the two-year-old case regarding the pipe bombs, as the FBI has consistently declined to provide transparency on the matter.

"Your failure to comply with our request is particularly concerning given recent media reports regarding the pipe bomb investigation," lawmakers wrote.

In a disclosure to the Washington Times, an FBI whistleblower revealed that the agency had identified the vehicle used by the suspect shortly after the placement of the bombs but has not taken further action in pursuing the individual involved.

"The FBI had surveillance video that showed the person entering a car with a visible license plate after exiting a Metro stop in Northern Virginia," the Times reported.

Former FBI agent Kyle Seraphin, who worked on the case, told the outlet that the agency "tied whoever the person was that dropped the bombs with [surveillance] cameras all the way through the train and getting into a car with that license plate." In addition, he told the Washington Times that both of the alleged bombs were inoperable.
