Hillary Clinton May Have Just Saved the Iran Deal Her support makes it unlikely GOP can prevail in Congress By John Johnson, Newser Staff Posted Jul 14, 2015 1:39 PM CDT 148 comments Comments In this June 15 photo, Hillary Clinton shakes hands after speaking in Concord, N.H. (AP Photo/Jim Cole, File) (Newser) – Hillary Clinton met with congressional Democrats on Capitol Hill today and gave what one described as a "full-throated" endorsement of the Iran nuclear deal, reports the Hill. Clinton's public comments were a bit more measured: "This is an important step in putting a lid on Iran's nuclear program," she said, before adding that she still has "concerns" about Iran's behavior. Still, Clinton's support of the deal might well ensure its survival, writes Colin Campbell at Business Insider. Here's the rationale: Congress has 60 days to review the deal, and while it can't block the agreement, it can try to "undermine" it by refusing to lift sanctions on Iran, reports the AP. President Obama already has promised a veto in such a scenario. To override, Republicans would need to pick up Democratic votes, and while some of the more hawkish Democrats might be willing to buck Obama, they probably won't be willing to go against their party's sitting president and its 2016 frontrunner, writes Campbell. In fact, it's "EXTREMELY unlikely" that would happen, tweets Mark Murray of NBC News.
