"The Senate bill would require a competed deal to be submitted to Congress, which could then vote to approve or disapprove the nuclear deal within 30 days. Sanctions on Iran could not be lifted during this consideration.

A vote to disapprove a nuclear deal with Iran would not kill it. President Obama could veto such a measure, and the House and Senate would then need two-thirds majorities to override his veto.

The administration initially opposed the legislation, arguing it could interfere with negotiations with Iran. The White House changed course after it became clear that the bill had strong support from Democrats."
