President Obama's goal of getting Congress to sign off his nuclear deal with Iran suffered a high-flying defection when Senator Charles Schumer's announced Thursday night that he will oppose the agreement. His decision triggered a sharp reaction in his home district in Brooklyn. NY1's Roger Clark filed the following report.

On the streets of Chuck Schumer's Brooklyn neighborhood, the word was out Friday morning on his decision to oppose the Iran Nuclear Deal.

"I'm upset. Because I think, he's more interested in representing APAC and Israel. And I think the President was really clear on why he should support it,“ said one Park Slope resident.

"I would have hoped he aligned with the president as well. I think it's a real shame that he hasn't and I hope there's still an opportunity to change his mind,” said another.

Schumer faced anger no matter what he did. Some Jewish New Yorkers, a key voting bloc, see the treaty as hurting Israel, and they demanded that Schumer oppose it. Now, Schumer, a Democrat, is defying President Obama, the leader of the Democratic Party. Some in Park Slope are especially upset that he did.  

"I really think he should have stuck with the President because I don't think there is much, you know,” said one resident. “I think it's more about nuclear arms and that's what the president is interested in. I think Senator Schumer is more about Israel."

Not everyone NY1 talked with disagreed with the Senator though.

"I'm more for Schumer, because I think  that Iran may end doing something that is detrimental to the country," said one resident.

"I do like Schumer, so I think he can be independent,” said another, “And I'm not so sure this is a great deal, so I think he made the right decision."

Now some supporters of the deal say they are fearful Schumer's has increased the likelihood Congress will kill it.

"If Obama can't get the support of the Democrats, he is going to lose," said one resident.

“I don't see any other options, so I wish that more senators would get behind it. I wish that more politicians would get behind it, and that it wasn't such a politicized issue," said another.

And some folks say they still haven't totally made up their own minds on the deal.

"I'm not sure that I've seen a viable alternative and I'm not sure how to get back to the negotiating table now,” said one resident.

One Park Slope resident NY1 spoke with was so aggravated by the senator's announcement, he had already left a phone message at Schumer's office and complained on his Facebook page - a double dose of disapproval.
