With a nurse monitoring the blood pressure of one panel member, the jury in Oliver North's Iran-Contra trial resumed deliberations Tuesday.

The 12 members beginning their fourth day of considering North's fate have yet to actually discuss his guilt or innocence, with their time so far spent reviewing documents."We are reading through documents that pertain to charges," jury foreman Denise Anderson said in a note to the judge Monday, adding, "No talking."

Juror Jean Johnson, 53, experienced bouts of high blood pressure Monday and a note sent out to the judge in the afternoon asked for a nurse to take her blood pressure. The monitoring continued Tuesday.

Federal court rules provide that a jury can proceed with 11 members at a judge's discretion. Losing two members, however, would in all likelihood result in a mistrial. There is a provision under which a jury could reach a verdict with fewer than 11 members if both sides agreed to it and the judge approves it.

North is charged with 12 criminal counts, including lying to Congress and to the attorney general during the Iran-Contra affair, illegally converting traveler's checks to his own use and conspiring to defraud the Treasury.
