All week long, the debate over Iraq has been heating up on Capitol Hill. During testimony by Gen. Richard Myers at the Senate Armed Services Committee on Friday, the scene turned from questioning by committee members to arguing among the members. Democrats and Republicans fought over the number of hearings, and the attention the hearings are putting on the prison abuse scandal. On the Senate floor, Sen. Mark Dayton (D-MN) called for bringing U.S. troops home, while Sen. Orrin Hatch (R-UT) said calls for pulling out would hurt American efforts in Iraq. NPR's David Welna reports.
