The US administration warns the Congress that passing new sanctions against Iran will prove to the world that America negotiates in bad faith. White House spokesman Jay Carney says passage of new sanctions will undermine efforts to achieve a peaceful resolution of the standoff over Iran\'s nuclear program. He stated that any new sanctions would give the Iranians Quote-- an excuse Unquote to push the terms of the Geneva nuclear agreement to the side. The latest push by the White House comes as several groups of Republican and Democratic senators are making efforts to target Iran with a new set of sanctions. Carney added that if Tehran failed to abide by the terms of the deal, the White House would support new sanctions against the country. According to last month\'s Geneva deal, the U-S and its Western partners made a commitment to refrain from imposing new sanctions for six months. Show Less >>
