Senator Barbara Mikulski of Maryland became the 34th senator to declare that she will vote in favor of the nuclear agreement with Iran. That means that if a motion of disapproval passes the House and Senate, President Obama has declared he will veto it. Overriding a presidential veto requires a two-thirds majority of both houses of Congress. Thirty-four senators is one more than a third, so a presidential veto cannot be overridden. Now the Democrats will attempt to get seven more senators so that they can filibuster and prevent a motion of disapproval from being voted on. The last day that Congress can consider a motion of disapproval is September 17. Photo from The Hill.
