Closing arguments in the trial that began January 23 are slated to begin Tuesday.

This past Friday, after the court's week had ended, Libby's defense attorneys filed papers asking the judge to allow a statement of "good faith" to be read to the jury.

"Evidence of good faith can negate the specific intent to commit the crimes," Libby's lawyers wrote, citing as evidence Libby's testimony to a grand jury in March, 2004 that eventually indicted him on charges that include perjury and obstruction of justice.

"He describes his efforts to recall accurately the conversations he was asked to recount, and explains how and why any inaccuracies may have innocently occurred," said the defense counsel.

"If the evidence in this case leaves you with a reasonable doubt as to whether Mr. Libby acted with criminal intent or bad faith, you must find Mr. Libby not guilty," his lawyers wrote as part of the proposed statement.
