Bill Cosby's Attorney is not happy with CNN and their reporting.

Attorney Martin Singer, has fired off a heated legal letter to CNN accusing it of a smear campaign against the comedian.

In the letter to CNN president Jeffrey Zucker, Singer said that CNN decided not to use an interview with Beverly Johnson’s live-in boyfriend from 2006-2009, Mark Burk, because he didn’t corroborate her story of being drugged by the “Cosby Show” star for an upcoming special planned by the cable news network.

“We continue to be shocked by CNN’s ongoing refusal to investigate and run balanced stories about my client,” Singer wrote in the letter obtained by TMZ.

“While airing untested stories from accusers who have seemingly been subject to little or no vetting,” Singer continued, “CNN takes the opposite approach and with anyone who comes forward with information undermining accusers’ claims or with relevant information supporting Mr. Cosby.”

According to Singer, CNN reporters interviewed Burk, who told them that Johnson had never made a negative comment about Cosby and even said she admired the TV star and saw him as a mentor during the time they lived together. Singer accuses the CNN reporters of trying to “manipulate and coerce” Burk into saying statements that supported Johnson’s accusations. And when he wouldn’t corroborate Johnson’s account of events with Cosby, the reporters began attacking Burk and his background. Burk offered to send supporting documents for his statements, but CNN ultimately decided not to use his interview.

“This reckless approach to ‘journalism’ is outrageous,” the attorney wrote. “Accusers are being given a national platform by CNN without first exercising the most rudimentary journalistic investigation as to their claims and motivations. In contrast, CNN disregards and attacks sources with anything positive to say about my client or with relevant information undermining allegations that have been made.”
