Seem like you are incapable of having an adult conversation without feeling the need to first try to belittle or name call the person you having a discussion with. I do disagree with your claim. From my research, what Corker did was push legislation that would ultimately grant CONGRESS power to review the deal. To me, this is the right role of congress. This legislation was supported by overwhelming BIPARTISAN majority in BOTH house and senate. In the senate if passed 98 -1. In essence it granted Congress the opportunity to review the Iran nuclear deal BEFORE sanction were lifted on Iran. 
It is better explained here:

The Iran deal, like  in many deals and negotiation, there is give and take in order to come to an ultimate agreement. I am in favor of the Iran deal as brokered by the US, China, Russia, Germany, France, GB primarily because it keeps nuclear weapons out of the hands of Iran.
