Rep. Dan Kildee (D-Mich.) went "On The Record" tonight about the ongoing fight to get a former Marine released from an Iranian jail. 

For more than three-and-a-half years, Amir Hekmati has been jailed in Iran’s worst prison after being accused of espionage. However, his family claims that he was just visiting relatives in Iran.

Kildee said that Hekmati doesn't want his freedom "to be a condition or part of an exchange regarding Iran's nuclear capabilities."

Rep. Kildee: Can't Accept Iran Nuke Deal Unless Jailed Marine Is Released

"He certainly wouldn't want to be traded for something that makes the world a less safe place," Kildee stated. "But it's pretty tough for us not to consider all of Iran's behavior when we value this agreement, if there is an agreement. So it's difficult."

Kildee remarked that he thinks it's "interesting" that Iran would refer to the U.S. as a "hostile government," while they are trying to rejoin the international community. 

"Negotiation diplomacy is by definition not a hostile act, it's an act of trying to work things out," Kildee added. "We hope they get the message that if they want to be taken seriously, they can't hold political prisoners."
