Senator Chuck Schumer announced Thursday night that he would oppose Obama’s Iran deal. The long-discussed diplomatic strategy would involve limiting Iran’s nuclear program, which has implications for U.S. allies in the Middle East. Schumer, who is viewed as one of the most powerful Jewish voices in Congress could lead other Democrats to have second thoughts about the proposal. His primary concern is that Iran could build a nuclear weapon in ten years as the first decade of the agreement doesn't have harsh enough restrictions. Representative Eliot Engel followed Schumer’s lead in the House and announced his opposition to the deal Thursday as well. Collectively 12 Senate Democrats have voiced their support for the deal.
