U.S. President Barack Obama dropped his opposition on Tuesday to a bill giving Congress a voice on a nuclear deal with Iran after members of his Democratic Party negotiated changes to the bill that had won strong support from both parties.

White House spokesman Josh Earnest said Obama, who had said he would veto the proposed bill because it could scuttle the emerging Iran deal, could accept compromises that drew bipartisan Senate support ... The compromise bill passed the Senate Foreign Relations Committee unanimously and is expected to pass the full Senate...

It requires the Obama administration to send the text of a final agreement to Congress as soon as it is completed, and blocks Obama's ability to waive many U.S. sanctions on Iran while Congress reviews the deal.

It allows a final vote on whether to lift sanctions imposed by Congress in exchange for Iran dismantling its nuclear capabilities.
