President Obama urged Congress on Monday to "give diplomacy a chance," imploring lawmakers to hold off on additional sanctions against Iran as negotiators seek to take advantage of a six-month interim deal.
"It's going to be difficult, it's going to be challenging, but ultimately this is how diplomacy should work," Obama said, adding that the negotiating window formalized over the weekend should give world powers "the time and space" they need to formalize a permanent deal with Tehran.
Under the deal with Iran, the U.S. is loosening economic sanctions in exchange for a freeze to aspects of its nuclear program. Weapons inspectors will also be granted greater access to Iranian facilities.
But a bipartisan group of senators, including more than a dozen Democrats, has said it wants to pass legislation that would ramp up penalties on Iran if it fails to strike a long-term deal.

Over the weekend, Obama said in a statement he would veto that legislation and that the bill endangered negotiations with Iran.
And on Monday, press secretary Jay Carney said Congress should wait to evaluate Iran's seriousness, rather than potentially disrupt the process.
“We believe we have the opportunity to test whether or not this can be resolved between the international community and Iran peacefully, which is the preferred way it would be resolved,” Carney said.
