I've heard this too but I can't imagine the reasoning. Can you post the pages where it appears?
From the WP. Anything but a conservative source.

"Wilson's assertions -- both about what he found in Niger and what the Bush administration did with the information -- were undermined yesterday in a bipartisan Senate intelligence committee report.
The panel found that Wilson's report, rather than debunking intelligence about purported uranium sales to Iraq, as he has said, bolstered the case for most intelligence analysts. And contrary to Wilson's assertions and even the government's previous statements, the CIA did not tell the White House it had qualms about the reliability of the Africa intelligence that made its way into 16 fateful words in President Bush's January 2003 State of the Union address."
IMO, if this loser institutes a civil action against Libby, it is likely he will wind up in jail after the defense gets through with nailing him in all his lies.
