Miller's inaccurate info may offer Libby a loophole:

Miller disclosed this weekend that her notes of a conversation she had with I. Lewis "Scooter" Libby on July 8, 2003 stated Cheney's top aide told her that the wife of Bush administration critic Joseph Wilson worked for the CIA's Weapons Intelligence, Non-Proliferation, and Arms Control (WINPAC) unit.

Wilson's wife, Valerie Plame, never worked for WINPAC, an analysis unit in the overt side of the CIA, and instead worked in a position in the CIA's secret side, known as the directorate of operations, according to three people familiar with her work for the spy agency...

Whether it came from Libby or Miller's notes, former federal prosecutors and investigators said the incorrect information provides a significant lead for Fitzgerald and FBI agents to follow. It could suggest Libby thought Plame was not an undercover spy, and therefore couldn't have knowingly revealed her occupation, or that he got his information from uninformed sources, they said.

Meanwhile the Democratic National Committee claims a majority of the nine members of the White House Iraq Group have been questioned by Mr Fitzgerald.
