Jailed Washington Post reporter Jason Rezaian should learn his fate "within a week" after his secretive trial on accusations of spying on Iran ended August 10, his lawyer said.
His newspaper called the trial a "sham" and "sick brew of farce and tragedy." Rezaian spoke in his own defense at the final hearing.
The 39-year-old Iranian-American has been in custody more than a year on charges condemned as false by press freedom groups.
Outside the court, Rezaian's mother read a defiant statement, saying her son was an innocent victim of bad diplomatic relations between Iran and the United States.
The journalist, who has suffered poor health in prison, was "paying the price of the suspicion, the animosity, and the paranoia between the two countries," Mary Rezaian said.
Martin Baron, the Post's executive editor, said "it remains unclear even to Jason's lawyer what might happen next."
"The process has been anything but transparent and just, and that pattern persists. The only thing that is clear is Jason's innocence," he said.
