WASHINGTON, March 3 (UPI) -- The jury in the Washington perjury trial of I. Lewis Libby asked the judge for clarification on reasonable doubt before ending deliberations for the weekend.
A note from the jury to the judge appears to show that jurors are wrestling with Libby's claim that his misstatements to the FBI and a grand jury were a result of a memory lapse, The New York Times reported.
"We would like clarification of the term 'reasonable doubt,'" said the note to Judge Reggie Walton. "Specifically, is it necessary for the government to present evidence that it is not humanly possible for someone not to recall an event in order to find guilt beyond a reasonable doubt?"
Libby, former chief of staff to Vice President Dick Cheney, is charged with perjury and obstructing the investigation into the outing of CIA agent Valerie Plame Wilson.
The jury has been deliberating for almost two weeks.
