Senator Bob Corker, who chairs the Senate Foreign Relations Committee, said on Tuesday that he sees an "overwhelming" vote to pass the Iran nuclear review bill as soon as Thursday, Reuters reports.

Corker, a Republican, told reporters at the Capitol that leaders were still working out a way to allow the Senate to consider amendments to the bill, which would allow Congress to review an international nuclear agreement with Tehran before most sanctions on Iran could be waived.

"My sense is that Thursday there's a very good chance that we'll have an overwhelming vote," Corker was quoted as having said.

The legislation was approved last month by the Senate Foreign Relations Committee by a 19-0 vote, but last week a dispute arose among Republican senators over amendments to the legislation.

All 67 proposed amendments to the bill have been offered by Republicans, noted Reuters.

If approved, the measure would mandate that President Barack Obama submit the text of any pact to Congress and bar the administration from suspending congressional sanctions on Iran for 60 days.

In that time, Congress would hold hearings and have a chance to approve, disapprove or take no action on the agreement, the legislation says.

Obama had originally threatened to veto the bill as a threat to ongoing nuclear negotiations with Iran, until leaders of the foreign relations panel agreed on a compromise that removed many of the measure's strictest provisions.
