Minority Leader Nancy Pelosi praised House Democrats at her weekly news conference Thursday for initially opposing an Iran nuclear bill sponsored by Sen. Bob Corker, linking congressional opposition to a compromise later reached by Corker and Sen. Benjamin L. Cardin, the ranking member on the Senate Foreign Relations Committee. In expressing her support for the compromise bill, Pelosi also called the legislation “innocuous,” saying, “I don’t think we need any legislation.” “It’s much different from the original Corker bill, … Congress can always act,” Pelosi said. “But the Corker bill in the form that it was, was harmful. I don’t think it’s as harmful now.”
