Wife of Pastor Saeed Abedini: 'I Couldn't Stop My Tears' When He Was Freed

It’s been a long road for Amir Hekmati, the former U.S. Marine who four and a half years ago was wrongly convicted of espionage in Iran.

This weekend, Hekmati and four other Americans were finally told:  you’re coming home.

“It’s a great day,” Hekmati’s friend and fellow Marine, Nick Kaywork, said on Fox and Friends.

“I just can’t get the smile off my face today that he’s finally out of Iran.”

Kaywork, who helped campaign for his fellow serviceman’s release throughout the ordeal, called Hekmati “a great friend” and “fantastic Marine.”

He shed light this morning on some of the conditions Hekmati had to endure in his long captivity.

“He suffered long bouts of isolation. He was purposely given lithium, so that they could get him addicted to it. And then they took it away from him, so he could experience withdrawal symptoms.

They would whip the bottom of his feet.

Obviously, they coerced a confession out of him early on, which led to his conviction in Iran of espionage. And they charged him with a death sentence, but fortunately it was reversed.”

Remarkably, even through all these years, Hekmati “never really wanted to be part of a political process, never wanted to be a political pawn," said Kaywork.
