capacity to enrich is a problem. i think this agreement does that. i've also said over time i think the sanctions, if there was going to be sanction relief it should be delayed until we see sufficient iranian compliance. then the third thing about the agreement that bothers me is that it allows for sales of advance weapons like even ballistic missiles to iran. it would be a huge mistake for the world to begin selling advanced repenry to iran again. i won't be able to support the agreement. it doesn't address any of the things. i did vote for the corker bill. i think it is sometimes mischaracterized. the bill says the agreement has to come back and be voted on. the president objected to corker's bill and in the end it was passed and the president went along with it. the bill does have to come back and be voted on. there will be a chance -- >> but you didn't need the corker bill. it's in the constitution. you're a libertarian. you're a constitutional
