White House says it would veto Iran sanctions bill Twenty-six US senators introduced new Iran sanctions legislation earlier Thursday, despite an intense White House lobbying campaign. The Nuclear Weapon Free Iran Act, introduced by Senate Foreign Relations Committee chairman Robert Menendez, fellow Democratic Senator Chuck Schumer and Republican Senator Mark Kirk, would kick in should Iran violate the temporary deal or should negotiators fail to reach a comprehensive final agreement. "Current sanctions brought Iran to the negotiating table and a credible threat of future sanctions will require Iran to cooperate and act in good faith," said Menendez in a statement introducing the legislation. It was not immediately clear if or when the bill could see a vote on the Senate floor. A vote this year is highly unlikely, with the Senate set to recess this week until early 2014. Senate Majority Leader Harry Reid has indicated he is opposed to bringing such a bill to the floor in January, saying he agreed with the Obama administration's call to give the delicate negotiations a chance to work. Should the landmark interim deal collapse, the proposed sanctions would require Iran to reduce its oil production and would apply new penalties to the Islamic republic's engineering, mining and construction industries. The new legislation was introduced as negotiations were set to resume Thursday in Geneva between Iran and world powers in the so-called P5+1: the United States, China, Britain, France, Russia and Germany.
