the position. Metzler was ordered to report directly to the new Executive Director, and a United States Department of Veterans Affairs staff person assigned to assist him. McHugh also established a new Army National Cemeteries Advisory Commission to review Arlington National Cemetery's policies and procedures and provide additional recommendations. Former U.S. Senators Max Cleland and Bob Dole agreed to co-chair the commission. Patrick K. Hallinan, Director of the Office of Field Programs for the Department of Veterans Affairs, was named the Acting Superintendent of Arlington National Cemetery, effective upon Metzler's retirement. In June 2011, James Gemmell, former director of the Fort Snelling National Cemetery, was appointed as the cemetery's deputy superintendent. On June 16, 2010, The Washington Post notified the cemetery's new superintendent, Patrick K.

On July 27, 2010 SHSGA released documents criticizing the oversight of the cemetery by Army senior managers. The managers named included Claudia Tornblom, deputy assistant secretary of the Army for civil works, Edward M. Harrington, the Army's deputy assistant secretary for procurement, and Major General Richard Rowe, former commander of the Military District of Washington.
