Federal prosecutors revealed in court filings that federal agents seized over 150 pipe bombs and other explosive devices in a December raid on the Virginia home of Brad Spafford. This seizure is described as the largest by number of completed explosive devices in FBI history. Spafford was initially charged with possessing an unregistered short-barrel rifle, with additional charges likely related to the explosives. Prosecutors cited evidence of political extremism, including Spafford’s alleged use of President Joe Biden's images for target practice and comments supporting political assassinations.
