For nearly two years ABC News has been sitting on a special report by Diane Sawyer, who had gone out and interviewed prostitutes – both illegal ones and the ones working at the only legal US brothels in Nevada. The report had never aired amid criticism that it was tawdry and just pandering for ratings. But now that Eliot Spitzer, a/k/a “Client No. 9,” and his exploits with “Kristen” have become front page news, forcing Spitzer to resign as Governor of New York, prostitution is a hot, pertinent topic. Part one of Sawyer’s “Prostitution in America: Working Girls Speak” will air Friday (3/21) on ABC’s 20/20 at 9:00 pm ET.
