The government's rebuttal focused yesterday on summations made earlier on behalf of two other defendants. The prosecutor, Patrick J. Fitzgerald, sharply rejected defense assertions that one defendant, Wadih El-Hage, was a loyal American who had traveled frequently as part of his work in Mr. bin Laden's legitimate businesses.
''The mask has been stripped away,'' Mr. Fitzgerald said. ''He is what he did. He worked for a group that he knew was fighting against America. He wanted them to succeed and he helped every way that he could, whether it be fake passports, coded messages, taking trips to see the boss in the cave in Afghanistan, or just coming into this grand jury in this building, raising his hand, and lying through his teeth.''
