Radical lawyer Lynne Stewart got 28 months in prison this week for helping the blind sheik, a client of hers called Omar Abdel Rahman, communicate with his followers in Egypt.
Mohamed Yousry, Stewart's translator, a U.S. citizen born in Egypt who also worked for ABC News and Fox News, was convicted and sentenced to 20 months.
Yousry, a non-Muslim married to a born-again Christian, told ABC News in an exclusive interview before the sentencing that the FBI offered him a chance to avoid indictment -- if he would wear a hidden microphone to gather evidence against Stewart and Clark, who was also part of the blind sheik's defense team.
"I told them no," Yousry said.
Clark has been a passionate critic of the U.S.-led war on terrorism, and a controversial defender of some high profile enemies of the United States.
