The judge in Oliver North's trial said Wednesday he imposed a longer daily work schedule on the jury and said he isn't surprised the panel is in its 11th day of deliberations without reaching a verdict.

U.S. District Judge Gerhard Gesell said in a court session that he initiated the move to have the jury start promptly at 9 a.m., take a half-hour for lunch and stay until 5 p.m. That schedule began Tuesday.Gesell said that due to health problems among some jurors early in the deliberations, the panel had been working more limited hours and "they had gotten used to a shorter" schedule. One panel member was experiencing high blood pressure and a few others had colds, but all are now in good health.
