Vote count in favor of Iran deal climbs to 30 in US Senate
Democratic Sen. Tom Carper on Friday became the 30th senator to announce support for the Iran nuclear deal, as momentum for the White House-backed agreement grows.
If Senate Democrats can amass 41 votes in favor of the deal, they could block passage of a congressional resolution to disapprove of the deal.
If that doesn't happen and the Republican-led Senate votes to disapprove of the deal, President Barack Obama has vowed to veto it. Democrats then would need 34 votes -- four more than they have now -- to prevent a congressional override of the presidential veto.
A vote on the nuclear deal the U.S. and other world powers negotiated with Iran is scheduled for early September.
