There's an excellent (and lengthy) post by Glenn Greenwald at Salon.com that deals with false reports by ABC's Brian Ross regarding a connection between the 2001 anthrax attacks, Iraq, and 9/11. Excerpts are below, but the entire piece is worth reading.

"At one of the most critical times in American history -- the weeks following the 9/11 and anthrax attacks -- ABC News and Brian Ross published multiple, highly inflammatory reports, aggressively linking Iraq to the anthrax attacks, which turned out to be completely false. Accompanying those false anthrax reports, ABC News frequently linked Saddam to the 9/11 attacks as well -- such as when Cokie Roberts, during an interview with Donald Rumsfeld immediately following one of Ross's Saddam-anthrax stories, referenced "the confirmation that Mohammed Atta met with an Iraqi intelligence official."

While ABC, from the beginning, noted that even the White House publicly denied the bentonite story, they have never retracted, corrected or even explained their false reports. When I spoke with ABC News Senior Vice President Brian Schneider last week, he repeatedly emphasized that ABC News' credibility rests with the fact that when they are wrong, they quickly and clearly correct their errors.

Yet -- more than five years later -- why do they continue to allow these extremely damaging Saddam-anthrax reports to go uncorrected? The New York Times published a lengthy examination of its own culpability in publishing false reports about Iraq's WMD program long after those reports were published. Why hasn't ABC done that with these anthrax reports?"
