US official to share details with lawmakers about Iran nuclear side deal

Undersecretary of State Wendy Sherman says she'll tell senators in a classified briefing what she knows about the separate document between Iran and nuclear inspectors that is part of the nuclear accord negotiated with Tehran.

Republicans have criticized the Obama administration, saying Congress has not been given access to the document, which they say is needed to decide whether to vote to approve the deal in September.

Sherman told the Senate Banking Committee Wednesday that she has seen provisions of the document, outlining technical aspects of how Iranian sites will be inspected to ensure compliance.

The administration is defending the nuclear deal, which aims to curb Iran's nuclear program in exchange for billions of dollars in economic sanctions relief.
