Secretary of State John F. Kerry plans to brief senators Wednesday on the recent agreement reached between Iran and western powers on Iran's nuclear program.
Kerry is expected to meet with senators in a secure location on Capitol Hill on Wednesday afternoon, according to Senate aides familiar with the plans.
The meeting comes as senators are still considering whether to move ahead with a new round of sanctions against Iran's oil sector. None of the competing proposals would begin unless Iran violated the agreement brokered last month in Geneva by Kerry and other top global diplomats.
On Tuesday, Kerry was on Capitol Hill testifying before the House Foreign Affairs Committee about the agreement.
Sen. Lindsey O. Graham (R-S.C.), one of the senators pushing for new sanctions, said he hoped a proposal would be formally unveiled this week.
"The Iranians are saying that if there's another round of sanctions coming from the Congress then they'll get out of the deal. Well, my view is that they would never be at the table without the sanctions," Graham said.
The senator said he supports Iran developing "a peaceful nuclear power program where the international community controls the fuel cycle." Absent that, however, Graham said sanctions should remain in place.
