Klan leader David Wayne Hull was arrested at his Washington County, Pennsylvania, home on February 13 for allegedly planning to blow up an abortion clinic.

Federal prosecutors charged Hull, a forty-year-old Imperial Wizard of the White Knights of the Ku Klux Klan, a small Pennsylvania-based group, with receiving, manufacturing, possessing and transferring a destructive device in violation of the National Firearms Act.

At a preliminary hearing in U.S. District Court in Pittsburgh on February 18, prosecutors accused Hull of trying to buy hand grenades from a witness cooperating with the FBI. According to an unsealed criminal complaint, Hull told the informant he was "going to blow up abortion clinics." Authorities say that Hull told the informant he made his car a "suicide bomb on wheels."

Hull is also accused of trying to trade a homemade disassembled pipe bomb to the informant in return for a cellular phone.

According to court papers, the informant saw Hull detonate two pipe bombs on his Amwell Township, Pennsylvania, property during a cross burning event last summer. Around that time Hull allegedly planned to give other Klan members lessons on building pipe bombs and asked the informant to conduct military training at Klan gatherings.

In July 2002, Hull attended the "Aryan Nations World Congress," convened by the Pennsylvania faction of the neo-Nazi Aryan Nations. He is also a follower of Christian Identity, a racist and anti-Semitic sect whose adherents believe that white people are God's chosen people, descended from the lost tribes of ancient Israel, and that minorities are soulless "mud peoples." David Hull's relative, Mark, described Hull beliefs as "sick", saying that he "once told me that he believed black people have no souls, and that they're like a dog."

According to the FBI's cooperating witness, three other unidentified people were helping Hull obtain explosives.

Hull, whose criminal record dates back to 1994, was arrested by the Pittsburgh Joint Terrorism Task Force, which consists of federal, state and local law enforcement agencies.
