LAUSANNE, Switzerland — Iran is considering demands for further cuts to its uranium enrichment program but is pushing back on how long it must limit technology it could use to make atomic arms, Western officials said Sunday.
Iran's potential movement on enrichment reflected the intense pressure to close a deal. But substantial differences between the sides may prove too difficult to bridge before Tuesday's deadline for a preliminary agreement, which is meant to set the stage for a further round of negotiations toward a comprehensive deal in June.
Foreign ministers and other representatives of Iran and the six powers in the talks have said there is a chance of succeeding by the deadline despite significant obstacles.
White House spokesman Josh Earnest said it was up to Iran to make that happen.
By accepting the restrictions, the Iranians would "live up to their rhetoric that they are not trying to acquire a nuclear weapon," he said on ABC's "This Week."
Meanwhile the House will act quickly to tighten sanctions on Iran if the administration’s nuclear talks with the Islamic Republic fail, House Speaker John A. Boehner said Sunday.
The Ohio Republican said on CNN’s “State of the Union” that he’s skeptical the Obama administration will reach a deal with Iran to rein in that country’s nuclear program.
“Frankly, we should have kept the sanctions in place so that we could have gotten to a real agreement,” he said.
