>> there any obstacles preventing the president from signing this deal?
>> not actual obstacles but there are plenty of political obstacles. he will you go there with this deal and you heard plenty of lawmakers this morning, all through sunday shows, even ones very critical of this deal say, well, the deal has been made. there is not a lot that can be done for now. here's the way to look at it. congress is giving the president a very short leash. any iota of something that makes it look like iran is not doing what is supposed to be done in this deal and you will see new sanctions bill. you will see pressure from capitol hill like we haven't seen before. remember, support for israel is bipartisan on capitol hill . israel has a very powerful constituency on capitol hill so if there is any movement here that iran doesn't look like they're doing this deal, the political pressure on the president to back out will be tremendous.
