A US Senate panel approved a measure Tuesday that would give Congress input on the fate of any final international deal to curb Iran's nuclear program.

In a display of bipartisan cooperation on what has been a divisive issue, the Senate Foreign Relations Committee voted 19-0 in favor of allowing lawmakers to review and potentially reject the final accord.

The vote came after panel chairman Bob Corker and top Democrat Ben Cardin struck a compromise on language in order to soothe concerns of the White House and some congressional Democrats.

"I think we've reached a balance here," Corker said.

A framework deal reached in Switzerland marked a breakthrough in a 12-year standoff between Iran and the West, which asserts Tehran is seeking to acquire a nuclear bomb -- a claim Iran denies.

Global powers must resolve a series of technical issues by a June 30 deadline for a final deal, including the steps for lifting sanctions on Iran, and remaining questions over the possible military dimensions of its nuclear program.

Several US lawmakers, including those who fear the deal might not be strong enough, want to weigh in and for Tehran to be afforded no sanctions relief until the review period is over.

Cardin and Corker were adamant that their bill would allow the talks between Iran and the so-called P5+1 -- Britain, China, France, Russia and the United States, plus Germany -- to continue unimpeded by congressional intervention.

"It is clear we will only act after the administration presents us with an agreement," Cardin said.

But he also stressed the White House would not be able to lift the nuclear-related sanctions on Iran without a congressional green light.

"Only Congress can permanently change or modify the sanctions regime," Cardin added.

- Support for terrorism -

Under the legislation, which heads to a full Senate debate and vote, the total review period would be reduced to 52 days, from the 60 days in earlier drafts.

That includes a 30-day review, plus 12 days for a possible veto by President Barack Obama and a 10-day window for an attempt to override such a veto.

Contentious language obligating Obama to certify to Congress that Iran was not engaging in terrorism was removed from the bill.

But it does require the president to make detailed reports to Congress on several issues, including Iran's ballistic missile work and its support for terrorism, particularly against Americans.

The measure appears to have support from the White House, which had threatened to veto the orignal bill out of fear it would derail the negotiations.

"What we have made clear to Democrats and Republicans in the Senate Foreign Relations Committee is that the president would be willing to sign the proposed compromise that is working its way through the committee today," White House spokesman Josh Earnest said shortly before the vote.

The panel convened after Secretary of State John Kerry came to Capitol Hill Monday and Tuesday to assuage concerns about the deal.

While some Democrats pressed Kerry on why lawmakers should let the White House move ahead with the Iran accord without their involvement, the top US diplomat provided "an irrefutably compelling case" for supporting the deal, House Democrat Jan Schakowsky said.

Senator Marco Rubio, who announced Monday he is running for president in 2016, withdrew his amendment that would have required Iran to recognize Israel's right to exist.

Some lawmakers warned extraneous elements could upend the bill, and Rubio acknowledged the importance of a securing congressional review of the Iran agreement.

Washington's powerful pro-Israel lobby AIPAC voiced approval of the measure, saying: "Congress should review any agreement to ensure it meets US objectives, and object if it fails to do so."

A final deal, the group said, "must be subjected to the constitutional system of checks and balances that is the bedrock of our democracy."
