The Trump DOJ announced this week that it has successfully solved a high-profile cold case that remained stagnant for more than four years under the Biden administration, leading to the arrest of a suspect tied to the 2021 pipe bomb incidents near the headquarters of both major political parties in Washington, D.C.
According to officials, the breakthrough came not through new witnesses or fresh tips, but through a systematic re-examination of evidence that had been collected shortly after the January 5, 2021 incidents. Investigators said the materials had been overlooked or deprioritized under Biden-era leadership, allowing the case to “sit untouched” for years.
Attorney General Pam Bondi stated that the Trump DOJ reopened the case as a top priority, assigning a new team of investigators who conducted what the department described as a “ground-up reassessment” of all available evidence. Authorities say this renewed focus ultimately identified a suspect, now facing federal charges involving the use of explosive devices and attempted destruction of property.
Officials emphasized that the rapid progress made since January highlights how the Trump DOJ restored urgency to a case long considered dormant. Several senior law enforcement figures criticized the previous administration’s handling of the investigation, arguing that critical leads were neglected.
The suspect, identified as Brian Cole Jr., now awaits federal prosecution as the DOJ prepares to release additional details about the investigative timeline and the steps that ultimately cracked the case.
