Senator Lindsey Graham, a possible 2016 Republican presidential contender, said the United States should put off a final nuclear agreement with Iran until after the U.S. election and said Democrat Hillary Clinton could get a better deal.

The South Carolina Republican sharply criticized President Barack Obama’s negotiating skills in talks to contain Iran’s nuclear program. The only candidate he mentioned by name as being able to do better was the Democrats’ presidential favorite.

“Keep the interim deal in place. Allow a new president in 2017, Democrat or Republican, to take a crack,” Graham told CBS’ “Face the Nation” program. “The best deal comes with a new president. Hillary Clinton would do better. I think everybody on our side except maybe Rand Paul could do better.”
