The White House launched a harsh attack on supporters of a Senate bill to impose fresh sanctions on Iran, suggesting that they have a hidden goal of drawing the country into another Mideast war. If supporters “want the United States to take military action, they should be up front with the American people and say so,” Bernadette Meehan, a spokeswoman for the National Security Council, said in a statement, Los Angles Times reported. “Otherwise, it’s not clear why any member of Congress would support a bill that possibly closes the door on diplomacy and makes it more likely that the United States will have to choose between military options or allowing Iran’s nuclear program to continue.” The White House argues that by driving Iran from the table, the tough new sanctions bill could undermine international negotiations aimed at an agreement to ensure that Tehran’s nuclear program remains peaceful. The White House statement, issued late Thursday, was the first time the administration had accused sanctions advocates of a concealed agenda. It escalated the administration’s criticism of powerful Democratic legislators whom the White House needs on many issues, including Sen. Chuck E. Schumer (D-N.Y.), No. 3 in Senate Democratic leadership, and Sen. Robert Menendez (D-N.J.), chairman of the Senate Foreign Relations Committee. President Obama has identified the Iran nuclear deal as a top foreign policy priority, and he and other top administration officials have conducted an unusual all-out lobbying campaign to stop the bill.
