Bill Clinton's former mistress Gennifer Flowers is threatening legal action to prevent the sale of documents that question the authenticity of the audio tapes of the phone conversations between her and the former US president.
Paul Barresi, a porn actor-turned-private detective, inherited the documents from his friend Jim Mitteager, a freelance reporter who died of cancer in 1997, the New York Post reported.
The tapes were first heard in 1992 when Flowers held a press conference and played some snippets of it.
Barresi has reports that were prepared in 1994 by audio experts who verified that it was Clinton's voice in the tapes, but found that the audio had been edited.
He has offered to sell the reports to the reality show 'Pawn Stars' for 15,500 dollars.
However, Flowers has denied tampering with the tapes and sold copies of the complete and unedited tapes for 75 dollars through Penthouse.
In her last message to Barresi, she wrote that she would sue if need be without any hesitation.
