Richard Cebull, Montana's chief federal judge, apologized to Obama after admitting he forwarded an email comparing African-Americans to dogs and implying that President Barack Obama's mother had sex with animals.
"I sincerely and profusely apologize to you and your family for the email I forwarded," said Cebull's apology letter, which was dated March 1. "I accept full responsibility; I have no one to blame but myself."
Cebull said he requested that the Judicial Council of the Ninth Circuit review the situation.
"Honestly, I don't know what else I can do," Cebull wrote.
Cebull admitted to sending the email on Wednesday. In an interview with the Great Falls Tribune -- the publication that obtained the email -- Cebull agreed the email was racist, but said he personally was not.
Cebull said he did not send the email because it was racist, but because it was 'anti-Obama.'
