Exclusive: U.S. and Iran closing in on one-page memo to end war, officials say

The White House believes it's getting close to an agreement with Iran on a one-page memorandum of understanding to end the war and set a framework for more detailed nuclear negotiations, according to two U.S. officials and two other sources briefed on the issue.

The big picture: The U.S. expects Iranian responses on several key points in the next 48 hours. Nothing has been agreed yet, but the sources said this was the closest the parties had been to an agreement since the war began.
