NORFOLK, Va. — A Virginia man pleaded guilty Friday in a federal case that accused him of stockpiling the largest number of finished explosives in FBI history and of using then-President Joe Biden’s photo for target practice.

Brad Spafford pleaded guilty in federal court in Norfolk to possession of an unregistered short barrel rifle and possession of an unregistered destructive device, according to court documents. Each count carries a maximum sentence of 10 years in prison. His sentencing is scheduled for December. Federal authorities said they seized about 150 pipe bombs and other homemade devices last fall at Spafford’s home in Isle of Wight County, which is northwest of Norfolk.

The investigation into Spafford began in 2023 when an informant told authorities that Spafford was stockpiling weapons and ammunition, according to court documents.

The informant, a friend and member of law enforcement, told authorities that Spafford was using pictures of then-President Joe Biden for target practice and that “he believed political assassinations should be brought back,” prosecutors wrote.

Two weeks after the assassination attempt of then-presidential candidate Donald Trump in 2024, Spafford told the informant, “bro I hope the shooter doesn’t miss Kamala,” according to court documents. Former Vice President Kamala Harris had recently announced she was running for president.
