This is something that we continue to push hard on irrespective of the nuclear deal, it’s a top priority for us to make sure that our people are treated fairly and on the face of it in the case of these individuals who’ve been held, they have not been and they are not being afforded the basic due process and legal rights that we afford visitors to our country so we're deeply concerned about it, we spend a lot of time pushing on it, and we will continue to do so . . . .
