The White House says it will continue with an expected push for sanctions against Iran, despite new reports that the regime has temporarily halted uranium enrichment in hopes of a nuclear fuel swap.  The U.S. and its allies have offered Iran a deal that would supply nuclear fuel cells for medical use. In return, Iran would be required to ship its enriched uranium to France and Russia. A senior administration official tells Major Garrett that the proposal remains on the table, but there is no indication Iran will accept the deal. The official says Iran's insistence on a simultaneous swap "does nothing to build confidence in their supposed peaceful intent."
