Bush at Bay: Fitzgerald Looks at Niger Forgeries

The CIA leak inquiry that threatens senior White House aides has now widened to include the forgery of documents on African uranium that started the investigation, according to NAT0 intelligence sources.

This suggests the inquiry by special prosecutor Patrick Fitzgerald into the leaking of the identity of undercover CIA officer Valerie Plame has now widened to embrace part of the broader question about the way the Iraq war was justified by the Bush administration.

Fitzgerald's inquiry is expected to conclude this week and despite feverish speculation in Washington, there have been no leaks about his decision whether to issue indictments and against whom and on what charges.

Two facts are, however, now known and between them they do not bode well for the deputy chief of staff at the White House, Karl Rove, President George W Bush's senior political aide, not for Vice President Dick Cheney's chief of staff, Lewis "Scooter" Libby.

The first is that Fitzgerald last year sought and obtained from the Justice Department permission to widen his investigation from the leak itself to the possibility of cover-ups, perjury and obstruction of justice by witnesses. This has renewed the old saying from the days of the Watergate scandal, that the cover-up can be more legally and politically dangerous than the crime.
