i see my time has expired and i know recognize ranking member mr. meeks. >> thank you. i'm not going to speculate because i don't think we should be speculating or giving our own opinions, or paraphrasing of what you are saying. i'm going to take you for what you are saying and not going to guess on what my thoughts are, e because we want to do an investigation to determine what we should learn from this. let me join that chairman and say to our gold star families how much we appreciate you and the heroes that lost their lives . i know there is nothing we can do to bring them back. they are indeed heroes for our country and i thank you for your sacrifices. i will tell you that no matter whether it is a democrat or a republican, i truly believe that we will always hold them dear and acknowledge the heroes that they are. thank you for being here. ambassador, you have worked tirelessly over the years to negotiate and implement the doha deal, as did many others in our government. i have some questions i want to ask, and based upon your experience, they are mostly yes or no.
