John Walker Lindh, 21, was not seriously injured in the attack at the federal prison in Victorville, California, officials said. The prison is about 85 miles northeast of Los Angeles.
Lindh attorney Tony West said in a statement the incident happened Monday as Lindh prepared for an evening prayer.
The investigation began after someone called the San Bernardino County Sun with an anonymous tip early Tuesday, The Associated Press reported.
"Yes, I'd like to inform your newspaper that John Lindh Walker (sic), who is incarcerated in Victorville, was assaulted this night by a white supremacist organization that is imprisoned there. Thank you," the male caller said in a voice message.
