Convictions for sex trafficking, child pornography and related crimes, in violation of 18 U.S.C. sections 1591, 2251A , 2251(b) and others, are affirmed over defendants' meritless claims that the district court: 1) deprived female defendant of a fair trial by denying her motions for severance of her trial and by making erroneous evidentiary rulings; and 2) deprived male defendant of a fair trial by denying his attorney's request to withdraw from the case, by admitting in evidence portions of his self-titled autobiography that give an account of his past thoughts and conduct; and by denying his request for a continuance following unexpected testimony from a government witness.
