Court Document: Former US Capitol Police Officer-Turned-CIA Failed Polygraph Test Regarding J6 Pipe Bombs
In December of 2025, the FBI identified the alleged pipe bomber and conducted a search on his home, and arrested Brian Cole Jr., 30, of Woodbridge, Virginia, after a “fresh review” of old evidence. The FBI claimed they found evidence during the search that suggested Cole Jr. was the person responsible for placing the inert devices at the RNC and DNC Headquarters on the evening of January 5, 2021.
Following his arrest, Cole, who is said to be autistic, sought bail in January 2026, but was denied by U.S. Magistrate Judge Brian Sharbaugh after Cole admitted to planting the bombs after hours of intense interrogation; however, he has pleaded not guilty to the two charges related to planting the explosive devices.
In November of 2025, a former U.S. Capitol Police officer, who now works for the Central Intelligence Agency, was identified as the alleged pipe-bomber by The Blaze’s Steve Baker. However, according to CBS News, the former USCP officer had an alibi: a video of her at home playing with her puppies that night.
In a new filing from Cole’s attorneys today, a new detail has emerged that wasn’t previously reported.
In a Motion filed this morning, it was learned that, “according to discovery produced by the government in this case,” “the FBI began investigating, questioning, and covertly surveilling” Kerkhoff “during the time it began investigating Mr. Cole.”
On November 6, 2025, Kerkhoff was interviewed by the FBI and took a polygraph examination.
She was asked two relevant questions: (1) “Did you place those pipe bombs?” and (2) “Did you place those pipe bombs that evening?” Ms. Kerkhoff failed the polygraph. The FBI polygraph examiner noted Kerkhoff’s “very controlled reaction to the news of her failing the polygraph and seemingly rehearsed responses to the examiner’s questions.”
On November 7, 2025, the filing reports that the FBI opened a file on Kerkhoff and issued subpoenas and preservation requests for electronic accounts.
On November 12, 2025, the same day the investigation into Mr. Cole was opened, the FBI “attempted to question Ms. Kerkhoff and Mr. Dickert at her residence.” The following day, they interviewed Kerkhoff’s dog walker.
Then, the next day, following the dog walker interview, Kerkhoff and Dickert were interviewed together by the FBI and an Assistant US Attorney (AUSA). A former FBI agent told The Gateway Pundit that this is “definitely a bit unusual” to interview them together, noting they’d never conducted a joint interview with an AUSA.
The filing states that Kerkhoff was surveilled the entire month of November 2025 without her knowledge and that a request had been sent to the CIA for her employment records. They also sent surveillance footage of her walking to a podiatrist, “likely for a gait analysis.”
Cole’s attorneys are now requesting subpoenas for the following information, according to the filed motion:

(k) documents and communications about services used to wipe publicly-available information about Ms. Kerkhoff; and (1) the phone number and carrier for any devices Ms. Kerkhoff used on January 5-6, 2021 provided by her employer.
In a post on X, The Blaze’s Steve Baker, who initially raised suspicion about Kerkhoff’s involvement in the planting of the pipe bombs, stated, “To all those who have criticized and attacked me these last five months, I forgive you…LOTS more to come.”
To all those who have criticized and attacked me these last five months, I forgive you. I do not forgive @dbongino or @FBIDirectorKash, and I demand Patel’s dismissal immediately. LOTS more to come. https://t.co/p5nRNV2CyB
