US-Iran Nuke Deal Not Likely as Deadline Nears

Insiders say there's little hope that Iranian and U.S. negotiators will come up with a framework for a deal on Iran's nuclear program within the next two weeks.

The best they can hope for is an agreement to hold more talks. That's not likely to satisfy critics of the negotiations in America and Iran.

Meanwhile, the Obama administration is putting the focus on Republican senators who sent an open letter to Iran's leaders.

Secretary of State John Kerry blasted the senators for their letter that said any deal will need congressional approval. Kerry said Congress will not and should not have a say in any final agreement.

But Senate Majority Leader Mitch McConnell, R-Ky., said the administration is dodging the real issues.

"Well, the administration would like to have a distraction," McConnell told CNN. "But the point is the substance of the matter. Are they or are they not about to make a very bad deal that will allow the Iranians, one of the worst regimes in the world, to continue to have their nuclear infrastructure?

Now comes word that the Iranians are making a new demand.

They want to keep an underground facility that has hundreds of centrifuges capable of enriching uranium for nuclear warheads.
