Libby is headed back to court to try to forestall his 30 month prison term in the CIA leak case.
WASHINGTON (CNN) - The federal judge who will decide whether to order Lewis "Scooter" Libby to prison or allow him to remain free pending the results of an appeal of his March conviction said Thursday he has received threatening phone calls and letters.
"In the interest of full disclosure, I have received a number of harassing, angry and mean-spirited phone calls and messages," U.S. District Judge Reggie Walton told the court at the start of the proceeding. "Some wishing bad things on me and my family."
"Those types of things will have no impact," Walton said. "I initially threw them away, but then there were more, some that were more hateful. They are being kept."
Lawyers for the convicted former aide to Vice President Dick Cheney are trying to keep their client out of prison while they appeal the case.
Walton has said he will hear arguments from the defense and prosecution before he makes his decision.

I. Lewis "Scooter" Libby leaves the courthouse in Washington last week after being sentenced to 30 months in prison.
WASHINGTON (CNN) - Special Prosecutor Patrick Fitzgerald urged a federal judge Tuesday not to delay former White House aide I. Lewis "Scooter" Libby's 2 1/2-year prison sentence in the CIA leak case.
Libby, the former chief of staff to Vice President Dick Cheney, has argued that he has a good chance of winning an appeal and should be allowed to remain free until that challenge has run its course.
U.S. District Judge Reggie B. Walton, who sentenced Libby to prison for lying to authorities and obstructing the investigation into the 2003 leak of CIA operative Valerie Plame Wilson's identity, has said he sees no reason to grant Libby's request.
ATLANTA, Georgia (CNN) The ten Republican candidates were asked whether they would pardon I. Lewis "Scooter" Libby, former chief of staff to Vice President Dick Cheney, who on Tuesday was sentenced to 30 months in prison for lying to investigators looking into the leak of a CIA operative's identity.
Texas Rep. Ron Paul, Former Virginia Gov. Jim Gilmore, California Rep. Duncan Hunter and Former Arkansas Gov. Mike Huckabee all responded "no," or "no, not without looking at the transcript."
Arizona Sen. John McCain: "He's going through an appeal process. We've got to see what happens here."
Former New York Mayor Rudy Giuliani: "I think the sentence was way out of line. I would see if it fit the criteria for pardon. I think what the judge did today argues more in favor of a pardon
because...this is excessive punishment."
Former Massachussetts Gov. Mitt Romney: "I will study it very closely if I'm lucky enough to be president, and I'd keep that option open."
Sen. Sam Brownback: "Yes. The basic crime here didn't happen."
Former Wisconsin Gov. Tommy Thompson: "I would make sure the appeal was done properly, and then I would examine the record."
Colorado Rep. Tom Tancredo: "Yes."

I. Lewis "Scooter" Libby leaves the courthouse in Washington on Tuesday after being sentenced to 30 months in prison.
WASHINGTON (CNN) - After Lewis "Scooter" Libby's sentencing Tuesday, the judge in the case released 350 pages of letters written to him by both Libby's supporters and detractors. Judge Reggie Walton says he weighed the letters when deciding Libby's 30 month sentence.
The collection includes letters from colleagues and friends of Libby, including Donald Rumsfeld, Henry Kissinger, Paul Wolfowitz and Chairman of the Joint Chiefs of Staff General Peter Pace (click here to read those letters).
Rumsfeld calls Libby "a truly honorable public servant," while Pace says he was "a team player."
Not all the letters are positive. One from "an angry citizen" asks the judge to impose "the longest possible prison term" on Libby.
