At the trial on 21 December, Hussein accused the United States of torturing and beating him.
The same day, Hussein's allegations were rejected by the White House, which called them "preposterous."

Hussein boycotted the last hearing two weeks ago after challenging the legality of the tribunal and telling the judge to "go to hell."
