Former US vice-presidential aide I. Lewis "Scooter" Libby, convicted in March of perjury and obstruction of justice, will be appealing the verdict according to documents filed in court Friday. Libby's defense team had previously planned to request a new trial, bids for which are rarely granted. Libby's appeal may focus on a decision by US District Judge Reggie B. Walton to allow prosecutors to present evidence to the jury that Libby's defense viewed as being prejudicial, such as White House briefing room videos which US Special Prosecutor Patrick Fitzgerald played to show Libby's eagerness to publicly conceal conversations he had with reporters about CIA official Valerie Plame.

Libby was convicted by a federal jury after 10 days of deliberation in a case that began January 23. Libby was convicted of two counts of perjury, one count of lying to the FBI and one count of obstruction of justice. He was acquitted on one count of lying to the FBI. Libby's sentencing is scheduled for June 5.
