FILE- In this Oct. 9, 2013 file courtroom drawing, defense attorney, Jeremy Schneider, left, represents accused terrorist Mustafa Kamel Mustafa, center, in Manhattan federal court, in New York. Opening arguments in Mustafa’s terrorism trial began in New York on Thursday, April 17, 2014. Federal prosecutors accused Mustafa of training and aiding terrorists in the 1990s while hiding in plain sight as the leader of a London mosque, while Mustafa’s attorney told jurors his client had never harmed Americans and did not participate in any of the acts charged in the case.
