Congressman Dan Kildee, who represents Flint's disrict, says news of Hekmati's hunger strike is worrying, but:
"I understand that he’s sitting there in the lonely and quiet of his own cell feeling like he’s isolated, where he can't see all the ongoing efforts on his case, where he would feel like he could do something to call attention to his case. He’s doing what I think he thinks he can do.
"We literally work on this case every single day. Our main goal, and hopefully Amir hears this, our main goal is to keep his case in frontal lobe of everyone who is paying attention to Iran, so that if a moment occurs when Iran see it’s in their interested to make a gesture towards the international community, they will see that the release of Amir Hekmati would be a tangible gesture that demonstrates that they are truly serious about becoming a member of the international community. "
