The FBI’s Washington Field Office (WFO) affirmed that there may have been “undercover officers” and “confidential human sources” inside the Capitol on Jan. 6, 2021, according to whistleblower testimony obtained by the Daily Caller News Foundation.

The FBI’s Washington Field Office requested the Boston Field Office open investigations into 140 individuals who took buses from Massachusetts to D.C. on Jan. 6., but denied the office’s request to see video proving those individuals were inside the Capitol, FBI whistleblower George Hill said during a Feb. 10 interview with the House Select Subcommittee on the Weaponization of the Federal Government. The office claimed they needed to “protect” the identity of possible undercover agents, according to Hill.

The Boston office initially opened cases on two individuals that “definitive evidence” showed were in restricted areas of the Capitol, Hill said. Because those individuals organized the buses to D.C., the WFO wanted cases opened on every individual on the bus.
