WASHINGTON (Reuters) - Vice President Dick Cheney's former aide, Lewis Libby, pleaded not guilty on Thursday to charges in the CIA leak probe, and his lawyer promised to fight it out in a public trial that could put a spotlight on how the White House made its case for the Iraq war.
"With respect, your honor, I plead not guilty," Libby told federal Judge Reggie Walton during his 10-minute arraignment.
