In news from Washington, Dick Cheney’s former chief of staff Lewis “Scooter” Libby has dropped his appeal in a perjury case stemming from the outing of CIA operative Valerie Plame. Libby was found guilty in March of lying and obstructing an investigation into who blew Plame’s cover after her husband Joseph Wilson criticized the Iraq war. President Bush commuted Libby’s two-and-a-half-year prison sentence in July, but Libby still had to pay a $250,000 fine. President Bush has not ruled out a full pardon for Libby.
