US President Barack Obama assured Americans on Saturday that a newly negotiated framework for a nuclear pact with Iran was a "good deal" as he sought public support for a diplomatic breakthrough that many in Congress oppose.
A day after placing calls to top US lawmakers to urge support for the agreement, Obama pressed his case that the deal would ensure Washington's longtime foe would not be able to build a nuclear weapon.
"It's a good deal, a deal that meets our core objectives, including strict limitations on Iran's program and cutting off every pathway that Iran could take to develop a nuclear weapon," Obama said in his weekly radio and Internet address, broadcast on Saturday.
"This deal denies Iran the plutonium necessary to build a bomb. It shuts down Iran's path to a bomb using enriched uranium," he said.
