WASHINGTON - Two US senators who wrote a tough sanctions bill against Iran said on Wednesday they would work with other members of Congress to push for action against Tehran if a potential deal does not dismantle Iran's nuclear program. New Jersey Democrat Robert Menendez, the chairman of the Senate Foreign Relations Committee, and Illinois Republican Mark Kirk said a 'good deal' would require strict limits on nuclear-related research, development and procurement and a robust inspection regime for decades in Iran. 'If a potential deal does not achieve these goals, we will work with our colleagues in Congress to act decisively, as we have in the past,' the two senators said in a statement.
