A Louisiana newspaper is pointing out discrepancies related to Brian Williams' coverage of Hurricane Katrina in 2005. 

The New Orleans Advocate has raised questions about the NBC Nightly News anchor saying at the time that he saw a body float by his hotel room in the French Quarter.

The report cites a doctor who said that he rode out the devastating storm in a trailer in the same neighborhood.

"We were never wet. It was never wet," said Dr. Brobson Lutz, a former city health director. 

Lutz also cast doubt on Williams' statement last year that he contracted dysentery by accidentally ingesting floodwater after Katrina.

Lutz said he did not treat any human cases of dysentery and never heard of any cases being treated after the storm.

Williams admitted this week he had fabricated parts of a story he told several times about coming under fire while riding in a U.S. military helicopter in Iraq in 2003. 

He claimed to have "misremembered" certain parts of the incident after troops that were involved disputed that the chopper came under fire.

Howard Kurtz, host of Media Buzz, reacted on "America's Newsroom" this morning, explaining that he was in New Orleans with Williams at one point after Katrina. 

He said he heard the "dead body" story from Williams, but has no way of knowing whether it was true or not.

"I have no way of knowing whether this anecdote is true or whether he embellished it. ... Some of this may be piling on by this New Orleans newspaper," said Kurtz. 

Kurtz said NBC News has taken a "no comment" stance since Williams' apology Wednesday night. He said the network has no choice but to stand behind Williams, calling him "almost too big to fail." 

He said if a different reporter at NBC had admitted the same thing, he or she "would be lucky" to keep their job.
