Weeks after Iran signed a landmark deal with the permanent members of the UN Security Council plus Germany, more signs emerge that some members of the Congress are already preparing to torpedo it. Several key senators have asked intelligence officials to examine whether a new set of sanctions would derail the nuclear talks with Iran. The request was made by the chairmen of the Senate\'s banking, intelligence, and armed services committees, and the reply should be ready in less than a week. The senators have also asked intelligence officials to provide briefings to the chamber -- once every 45 days starting on February first -- on whether Iran is complying with the deal. Some members of Congress are pushing for a new list of sanctions against Iran. But the White House is calling on senators to hold off. It says new sanctions against Iran would make Washington appear to be acting in bad faith in its nuclear outreach to Tehran. Show Less >>
