Senate Foreign Relations Chair, Bipartisan Group of Senators Want New Sanctions Against Iran

May wait to hear from Kerry, who's returned from talks in Generva

Senate leaders showed bipartisan support Sunday for tougher sanctions on Iran following failed talks this weekend toward curtailing that country's nuclear-development program, but also indicated they would likely wait until after talking to Secretary of State John Kerry.

Kerry and other Western leaders wrapped up talks Sunday after failing to agree on a deal, which purportedly stalled when France rejected a list of demands on Iran because they were too generous to mean an easing of international sanctions.

Administration officials led by Vice President Joe Biden and including Kerry had persuaded senators late last month to delay considering a new round of penalties until after the Geneva talks.
