Brother of Jason Rezaian Urges More Action on Anniversary of Imprisonment

"I don't think that anybody's done enough until he's out," Ali Rezaian tells NBC News' Richard Engel.

Washington Post reporter Jason Rezaian has been held in Iran’s Evin prison for exactly one year now, and the Tehran bureau chief’s brother is, once again, publicly calling on the White House and other top U.S. officials to push harder to secure his release.

“You know, I don’t think that anybody’s done enough until he’s out,” Ali Rezaian told NBC News’ Richard Engel in an interview that aired on Wednesday’s edition of The Today Show.

“I know that they asked him a lot about his emails. They asked him about people that he knew, friends that he had,” said Ali. “They asked him about everybody who came to dinner at his house.”

Despite the landmark deal reached with Iran over nuclear weapons last week, Rezaian and three other Americans remain imprisoned under questionable charges. The Obama Administration has been sharply criticized by some members of the media for not tying the prisoners’ release to the negotiations, among them — CBS News’ Major Garrett. 

During a heated exchange with the CBS correspondent at a White House press conference last week, President Obama told reporters that “nobody is content” while the four American detainees are held in Iran.

“We are not going to relent until we bring home our Americans who are unjustly detained in Iran,” said the President in a speech to the Veterans of Foreign Wars in Pittsburgh on Tuesday.

The Post has since petitioned the UN Human Rights Council to aid in the release of Rezaian, due to the “arbitrary and unlawful” treatment of the journalist.

“An entire year, of course, now has passed and not one shred of evidence has been produced,” said the Post’s executive editor Martin Baron. “He was just a reporter doing his job and doing his job well and doing it fairly.”

Rezaian, whose closed-door trial is reportedly nearing its conclusion, could face up to 20 years in prison if convicted.
