The proposed Iran nuclear deal earned the support of three more Senate Democrats on Tuesday, locking in key support for President Obama’s top foreign policy priority.
California Sen. Barbara Boxer joined Sens. Tim Kaine of Virginia and Bill Nelson of Florida in expressing support Tuesday while on the other side of the Capitol, a resolution aimed at blocking the multinational agreement was formally introduced in the House. The moves come as Obama prepares to deliver a major address Wednesday to build support for the agreement, which was finalized last month in Vienna between Iran and a group of world powers led by the United States.
