“President Barack Obama has secured the support of 34 Senate Democrats for the nuclear deal with Iran, ensuring sufficient backing to sustain his veto of any legislation aimed at derailing the agreement,” NBC News reports.  

“Sen. Barbara Mikulski of Maryland on Wednesday became the 34th Senate lawmaker to announce that she’s supporting the deal… Momentum has been building in the White House’s favor all month. Just two Senate Democrats — Sen. Chuck Schumer of New York and Sen. Bob Menendez of New Jersey — have announced opposition to the measure, while all other Democrats have said that — despite some concerns with the agreement — it presents the best available option to prevent a nuclear threat from Iran.”  

“The next question will be whether or not Democrats muster sufficient support to block consideration of the measure entirely. If 41 senators back the Iran deal, Democrats will be able to filibuster legislation opposing it and block the disapproval measure from coming to the Senate floor.”
