A Virginia man pleaded not guilty Wednesday after being accused by the FBI of stockpiling the largest number of explosives bureau officials have witnessed.

A Virginia man pleaded not guilty Wednesday in a federal case that accuses him of stockpiling the largest number of finished explosives in FBI history and using President Joe Biden’s photo for target practice.

Prosecutors are fighting to keep a Virginia man behind bars after they say investigators found what could be the largest number of “finished explosive devices” in FBI history at his 20-acre home near Norfolk.

Investigators say they found the largest collection of explosive devices in FBI history at the Virginia home of Brad Spafford, who has been arrested.

Prosecutors say federal agents found one of the largest stockpiles of homemade explosives they’ve ever seized when they arrested a Virginia man on a firearms charge last month.

FBI investigation of a Virginia man led to what the agency calls its largest-ever seizure by number of finished explosive devices.
