Democratic Senate Minority Leader Harry Reid on Tuesday made a borderline anti-Semitic claim as he suggested in a TV appearance that Jewish influence in the State of New York led to Senator Chuck Schumer’s opposition to the Iran nuclear deal.

Schumer is only one of four Senate Democrats who have joined the Republicans in supporting a resolution to disapprove the Iran deal. To date, 41 Democrats have already announced they will support the deal. The Obama administration now has enough votes to uphold the agreement or even block a vote by filibustering the resolution of disapproval.

Taking a victory lap on CNN, Reid dismissed Schumer’s reasons for opposing the deal — including that Iran could create more trouble in the Middle East and could eventually build a nuclear bomb — as “fluff.”

Schumer is a “wonderful human being, but he has a constituency that is different than a lot of people’s,” Reid remarked.

“But there is no alternative. What he talks about is basically fluff,” the retiring Democratic leader said. “There is no alternative. What is the alternative? To have us alone? Have the international community walk away? We have negotiated this in good faith. It hasn’t taken months. It’s taken years. Years. This is the diplomatic breakthrough that will go down in history as one of the biggest diplomatic moves in the history of the world.”

Nonetheless, Reid told Wolf Blitzer that he doesn’t think Schumer’s opposition will hurt his chances to become the next Democratic leader at the end of 2016. “Chuck will be the next leader, I am confident of that,” he declared.
