spends the first day of his vacation at martha's vineyard. the big question will senator chuck schumer's opposition to the iran nuclear deal deliver a serious blow to his chances of passing through congress? joining me now haley jackson from martha's vineyard. >> you asked, alex, if this would be a serious blow to the deal on the iranian nukes. most likely not, at least that's the analysis. remember, even though senator schumer has come out against it and he is one of the top democrats in the senate. 15 other democrats have come out in favor of it including kirsten gillibrand including bernie sanders who, of course, is running for president. that said the white house has not ruled out that even on vacation president obama will be making a few phone calls in order to lock down support for this deal. his administration over the last several weeks has been really pushing this full court press to try to convince skeptical members of congress that they should back this deal. take a listen to what president obama said earlier this week about this. >> you don't negotiate deals
