The jury failed to reach a verdict Thursday after the first day of deliberations in the trial of suspected terrorist Abu Hamza al-Masri.
The jury is off on Friday but will return to court on Monday.
Al-Masri is charged with 11 counts in connection with a hostage-taking in Yemen in 1998, supporting a violent jihad in Afghanistan and a conspiracy to establish a terrorist training camp in Oregon in 1999.
During deliberations, the jury asked the judge to send them more notes on a phone call al-Masri made to a follower allegedly pertaining to the Oregon camp.
During the nearly five-week trial, al-Masri tried to explain statements he made in the past in which he praised Osama bin Laden and said the killing of non-Muslims was justified.
He also accused the government of editing his speeches to make him sound like a terrorist.
Al-Masri could spend life in prison if convicted.
