US President Barack Obama has signed into law a bill that would allow Congress to review and potentially reject any final nuclear agreement with Iran, Press TV reported.
The Iran Nuclear Review Act of 2015 was signed on Friday.
The legislation overwhelmingly passed the House of Representatives and Senate earlier this month.
The measure will allow for a 30-day review of any final nuclear deal with Iran.
During the reviewing period, Obama would be able to waive those Iran sanctions, which were imposed by the executive branch. However, the president would have to leave in place sanctions that Congress had previously drafted.
The bill would also force the Obama administration to certify, on a regular basis, that Iran is abiding by the terms of any nuclear deal.
The US and its negotiating partners reached a framework nuclear agreement with Iran in Switzerland on April 2.
Tehran and the P5+1 group - the US, Britain, France, China, Russia and Germany - are currently working to draw up a final accord by the end of June.
During a speech earlier on Friday, President Obama reassured American Jews that he still fully supports Israel.
"Our commitment to Israel's security and my commitment to Israel's security is and always will be unshakable," he said, adding that not doing so would be a "moral failing" on the part of him and his country.
He made the comments in honor of Jewish American Heritage Month at Adas Israel, Washington's most prominent conservative synagogue.
