Hawkish Republican Senator Lindsey Graham says there would be no chance at all for a possible nuclear agreement with Iran to be approved by the US Congress.

In an interview with Fox News on Sunday, Graham described the framework nuclear agreement reached between the Obama administration, its negotiating partners and Iran as “weak.”

“I don’t think there’s a snowball’s chance in Hell this framework will get approved by Congress after review,” the senator said.

“It is so weak in a time we need to be strong,” he said. “I don’t think any Republican or Democrat is going to allow that to become final.”

A new legislation would allow Congress to review any final nuclear agreement with Iran.

President Barack Obama had earlier threatened to veto the bill, but he said earlier this week that he would sign it.

“President Obama’s deal is deteriorating before our eyes,” said Graham.

Republican Senator Bob Corker, who introduced the bill, once again defended his legislation approved by the Senate Foreign Relations Committee on Tuesday.

There are a "lot of questions right now," Corker said on Sunday.

The legislation would allow Congress to review any deal before allowing sanctions to be lifted if approved by the House and Senate.

On Friday, US House Speaker John Boehner expressed hope that the White House fails to reach a final agreement with Iran over its nuclear energy program.

The Ohio Republican said that the Obama administration wants a nuclear deal with Iran at “any cost.”

"It just appears to me that the administration wants a deal at almost any cost," Boehner said. "That's a bad way to negotiate.”
