defense forces, it has come out just in the last few hours and said that the isis controlled area the caliphate as it were, has now been reduced to 75,000 square feet. but there is still isis fighters there, expects to announce victory over the caliphate in the next few days. what should happen next, the president wants to pull out. our general told barbara starr that when he was asked, he would not have advised to pull u.s. forces out. what do you think should happen next? >> so i agree with general votel. i also as i mentioned sit on those hearings and we had them as well on syria. there was definitely a degree of anxiety on the part of those witnesses they had, that i listened to, that they felt as though it wasn't the appropriate time to do at this time to withdraw those troops for a number of reasons, because they felt as though they were leaving people behind who needed more help and more support because they felt it would be too quick
