Just when it seemed that Fox News host Bill O'Reilly had side stepped the allegations that he lied about his war stories, now another charge surfaces.

HuffPo writes that new allegations have emerged that the Fox News anchor lied about being present at a suicide in Florida.

“He was in Dallas,” Tracy Rowlett, a former colleague of O’Reilly’s at Dallas station WFAA, told liberal watchdog Media Matters. “Bill O’Reilly’s a phony -- there’s no other way to put it.”

The Fox host has claimed on several occasions that he heard the gunshot that killed George de Mohrenschildt, a friend of JFK assassin Lee Harvey Oswald who committed suicide at his daughter’s home in Florida in 1977. O’Reilly originally made the claim in his 2012 book, Killing Kennedy. He repeated it during an appearance on "Fox & Friends" while promoting the book: “I was about to knock on the door where [de Mohrenschildt] was, his daughter’s house, and he blew his brains out with a shotgun,” O'Reilly said (see embedded video at the bottom of this piece). He made the claim again in an adaption of Killing Kennedy for younger readers.

Rowlett and Byron Harris, another of O’Reilly’s WFAA colleagues at the time, both say the embattled host was with them at WFAA’s Dallas headquarters when de Mohrenschildt died.

The station "would have reported it as some kind of exclusive -- and there was no exclusive -- if O'Reilly had been standing outside the door,” Harris said. Not only did WFAA run no exclusive, but the story was broken by The Dallas Morning News.

According to Rowlett and Harris, O’Reilly never mentioned while he was working at WFAA that he was present when de Mohrenschildt committed suicide.

“That came later," Rowlett said. “That must have been a brain surge when he was writing the book.”
