Senate leader seeks briefing on U.S.-Iran peace agreement

The leader told reporters he has not been briefed on the memorandum of understanding that outlines the agreement's framework. He urged the administration to send senior officials to Capitol Hill to brief lawmakers before U.S. and Iranian officials sign the document in Geneva on Friday.

Nuclear provisions draw attention The leader said much will depend on how the agreement addresses Iran's ability to develop a nuclear weapon. He noted that Trump and many Republican senators have said such development cannot be allowed. The leader added that Congress may need to vote on the deal, possibly through a resolution of disapproval, because of notification requirements tied to the nuclear components.

Vance electronically signed the agreement with Iran on Tuesday. Mohammad Bagher Qalibaf, speaker of the Iranian Parliament, has also signed it. The leader said members will have many questions about the deal and expressed hope that more details will be available before Friday.
