The FBI has arrested a suspect in the long-running investigation into the pipe bombs planted outside the Republican and Democratic national committee headquarters on Jan. 5, 2021, ending a nearly five-year mystery that has frustrated lawmakers, fueled conspiracy theories and cast a shadow over the government’s handling of the Jan. 6 attack.
Federal officials identified the suspect as Brian Cole, according to two senior law enforcement officials briefed on the case. Cole was taken into custody Thursday morning, an FBI official said. The Justice Department is expected to formally announce the arrest at a news conference later in the day.
The arrest represents the first major break in a case that has baffled investigators despite extensive public pleas for assistance, a half-million-dollar reward and the review of tens of thousands of video files. The FBI has said the individual who planted the bombs — one outside the DNC and another outside the RNC — acted alone and left the devices roughly 15 hours before they were discovered on Jan. 6, 2021.
An investigation that dragged on for years
For years, the lack of an arrest served as both an embarrassment for federal law enforcement and a magnet for unfounded speculation. Investigators interviewed more than 1,000 people and repeatedly urged the public to scour security footage for details, including distinctive Nike Air Max Speed Turf shoes with a gold logo worn by the suspect.
In early 2023, the bureau raised the reward for information leading to an arrest from $100,000 to $500,000 — a sign of mounting pressure as the wider Jan. 6 investigation continued to dominate national politics.
The pipe bombs were real and capable of killing or seriously injuring anyone nearby, the FBI has said. Their discovery on Jan. 6 diverted law enforcement resources at the very moment a mob of Trump supporters began storming the U.S. Capitol.
Conspiracy theories and political fallout
The absence of arrests helped spark conspiracy theories — including false claims that federal agents planted the bombs to entrap supporters of President Donald Trump. Just last month, the FBI publicly debunked another baseless allegation that a former Capitol Police officer had placed the devices.
Trump, who has pardoned Jan. 6 rioters — including individuals who assaulted police — did not include the pipe bomber in his sweeping clemency actions on his first day back in office this year.
Career agents credited amid political attacks
Former prosecutor Greg Rosen, who led the Justice Department’s now-defunct Capitol Siege Section, said Thursday the arrest underscores the persistence of the career FBI agents and prosecutors who have continued working the case despite years of political pressure from Trump and his allies.
“This is a testament to the incredible work of career FBI agents and prosecutors who have been working this case for years,” Rosen said. “While we don’t yet know all the facts, the American people should be proud of their work.”
The Justice Department has not released additional details about the circumstances of Cole’s arrest, what evidence led investigators to him, or whether more charges are expected.
The breakthrough closes one of the most visible remaining gaps in the sprawling Jan. 6 investigation — but also raises new questions about why it took nearly five years to identify a suspect in one of the most consequential domestic terrorism cases in recent memory.
