Asked about the meeting, National Security Council spokesperson Caitlin Hayden told BuzzFeed, “Congress has been an important partner in our efforts thus far. We will continue our close consultation, as we have in the past, so that any congressional action is aligned with our negotiating strategy as we move forward. Tomorrow’s meeting is part of these ongoing consultations, following on the recent P5+1 talks with Iran.”

In light of nuclear talks in Geneva and a nascent Iranian effort towards rapprochement with the West, the administration has publicly suggested that Congress hold off on new Iran sanctions recently. The State Department’s chief Iran negotiator Wendy Sherman asked the Senate Foreign Relations Committee in a hearing earlier this month to at least hold off until after Geneva talks that took place last week. “We do believe it would be helpful for you to at least allow this meeting to happen on the 15th and 16th of October before moving forward to consider these new sanctions,” Sherman said.

Iran hawks in Congress have remained steadfast in calling for new sanctions despite the relative flurry of U.S.-Iranian diplomacy.
