WASHINGTON, DC - DECEMBER 15: U.S. Sen. Bernard Sanders (I-VT) (R) asks questions as Sen. Frank Lautenberg (D-NJ) (2nd R) listens during a joint hearing on Nuclear Regulatory Commission before the Senate Environment and Public Works Committee and Clean Air and Nuclear Safety Subcommittee December 15, 2011 on Capitol Hill in Washington, DC. In October the four commissioners of the commission sent a letter to White House Chief of Staff William Daley expressing 'grave concerns" that commission chairman Gregory Jaczko's deficiencies as a leader could compromise nuclear safety. The hearing was to have a "Review of the Nuclear Regulatory Commission's Near-Term Task Force Recommendations for Enhancing Reactor Safety in the 21st Century."
