The Senate feud over key White House nominations boiled over on Capitol Hill last week as Republican leaders vowed to oppose the president's picks for the U.S. Court of Appeals for the D.C. Circuit, administration posts and national regulatory boards.

Majority Leader Harry Reid (D-Nev.) announced on July 11 that he plans to move forward with controversial, long-debated ­changes to the Senate's filibuster rules, a move that would strip the ability of Republicans to block votes on certain nominees. The announcement came one day after D.C. Circuit nominee Patricia Millett appeared on Capitol Hill for her confirmation hearing.
