A day earlier Obama told a news channel that the job of the US is to put in place mechanisms where they can verify what Iranians are doing and not doing when it comes to their nuclear program.
"The negotiations taking place are not about easing sanctions. The negotiations taking place are about how Iran begins to meet its international obligations and provides assurances not just to us but to the entire world that they are not..," Obama told the NBC news channel in an interview.
However, the Republicans launched a scathing attack on Obama on the reported deal.
Congressman Ed Royce, Chairman of the House Foreign Affairs Committee, said instead of toughening sanctions to get meaningful and lasting concessions, the Obama Administration looks to be settling for interim and reversible steps. He has convened a Congressional hearing on November 13.
