Disbarred defense attorney Lynne Stewart’s knowledge and intent when she passed messages from her imprisoned client to a terrorist group in Egypt was at the heart of intense arguments Tuesday at the 2nd U.S. Circuit Court of Appeals.

Defense attorney Joshua Dratel, trying to win a reversal of Stewart’s 2005 conviction for providing material support to a terrorist conspiracy, claimed that Stewart’s release of a statement by imprisoned Sheik Omar Abdel Rahman to his followers in the outlaw Islamic Group was protected by the First Amendment.
