Jury deliberations began Tuesday in the terror trial of Osama bin Laden's son-in-law in Lower Manhattan.
The jurors began deliberating at about noon and continued until before 5 p.m., when they sent a note to the judge to say, "We are all tired and mentally exhausted." The judge sent them home and they will continue to deliberate Wednesday.
Federal prosecutors say Sulaiman Abu Ghaith worked with al-Qaeda to try to recruit young Muslims to attack the United States after September 11, 2001.
His lawyers claim Abu Ghaith originally declined when bin Laden asked him to make a video explaining the reason for the attacks.
They say the videos he appeared in aren't enough for a conviction.
"I think the videos prove that Mr. Abu Ghaith said some horrible things that were recorded on camera and that were broadcast around the world. But the fundamental question is whether that represents a conspiracy to kill Americans and whether Mr. Abu Ghaith joined it. And that's what the jury is deciding," said Defense Attorney Zoe Dolan.
Abu Ghaith faces life in prison if convicted.
