In Washington, Lewis Libby entered a plea of not guilty in U.S. federal court Thursday. Libby resigned last week as Vice President Cheney’s chief of staff after being indicted in the case surrounding the outing of CIA agent Valerie Plame. Libby is charged with obstruction of justice, lying to the FBI and committing perjury before a federal grand jury. The Associated Press reports Libby is represented by two attorneys known for winning acquittals in white-collar criminal cases. Ted Wells has won acquittals for several corporate executives and former cabinet members. William Jeffress is a partner in the law firm Baker Botts, where former Secretary of State James Baker is a senior partner. The New York Times reports Libby was greeted at by several hecklers as he entered the courthouse. One admonished him for “taking the country to war on a pack of lies.”
