WASHINGTON (AP) — Once again, President Barack Obama is sending some Cabinet members to Capitol Hill to talk lawmakers into supporting the Iran nuclear deal.

Secretary of State John Kerry, Defense Secretary Ash Carter and Joint Chiefs Chairman Gen. Martin Dempsey plan to testify today before the Senate Armed Services Committee.

Energy Secretary Ernest Moniz is to join them.

And leading the effort to round up Democratic support for the deal is House Minority Leader Nancy Pelosi, who, along with House Democrats, will meet with Obama at the White House.
