WASHINGTON (Reuters) – Democratic U.S. Senator Barbara Mikulski said on Wednesday she will support the Iran nuclear deal, giving President Barack Obama the 34 Senate votes needed to sustain a veto of any congressional resolution disapproving of the deal.

Thirty-two Senate Democrats and two independents who vote with the Democrats now back the agreement.
