Congress is sending President Obama a bill that would give lawmakers the power to review and potentially reject a nuclear deal with Iran.

The House overwhelmingly passed the bill on a 400 to 25 vote.

The legislation, which Obama has said he would sign, gives Congress a chance to weigh in on what could be a significant international accord aimed at getting Iran to curb its nuclear program in exchange for relief from economic sanctions.

Negotiators from the U.S. and five other nations are rushing to reach a deal with Tehran by the end of June.

As lawmakers voted, Obama was at the Camp David presidential retreat trying to ease the fears of U.S. allies in the Gulf that are concerned about Iran’s rising influence in the region.
