Until the start of the 110th Congress, Souder was chairman of the House Government Reform Subcommittee on Criminal Justice, Drug Policy and Human Resources. The subcommittee had authorizing jurisdiction over the White House Office of National Drug Control Policy (ONDCP, known popularly as "the Drug Czar's Office"), and it oversaw all U.S. Government anti-narcotics operations, both foreign and domestic. In addition, the panel had broad oversight authority (covering the National Park Service, the White House Office of Faith-Based and Community Initiatives, public health programs, the Smithsonian Institution, etc.).
