Its primary areas of jurisdiction include taxation and other revenue measures; bonded debt of the United States; customs; reciprocal trade agreements; tariffs; general revenue sharing; Medicare, Medicaid, CHIP, TANF, and other Health and Human Services programs financed by a specific tax or trust fund; and social security.”

The United States Senate Committee on Homeland Security and Governmental Affairs is the chief oversight committee of the United States Senate. It has jurisdiction over matters related to the Department of Homeland Security and other homeland security concerns, as well as the functioning of the government itself, including the National Archives, budget and accounting measures other than appropriations, the Census, the federal civil service, the affairs of the District of Columbia, and the United States Postal Service. The committee had been called the United States Senate Committee on Governmental Affairs before homeland security was added to its responsibilities in 2004.The committee serves as the Senate's chief investigative and oversight committee. The chair of the committee is the only committee chair in the Senate with the power to issue subpoenas without a committee vote, though in practice, such unilateral subpoenas have rarely been issued in recent years.
United States Senate Committee on Appropriations
The United States Senate Committee on Appropriations is a standing committee of the United States Senate. It has jurisdiction over all discretionary spending legislation in the Senate. Its role is defined by the U.S. Constitution, which requires "appropriations made by law" prior to the expenditure of any money from the Treasury.
United States Senate Committee on Indian Affairs
The Senate Committee on Indian Affairs is a committee of the United States Senate charged with oversight in matters related to the American Indian, Native Hawaiian, and Alaska Native peoples. A Committee on Indian Affairs existed from 1820 to 1947, after which it was folded into the Committee on Interior and Insular Affairs. A new Indian Affairs Committee was created in 1977, initially as a select committee, as a result of the detachment of indigenous affairs from the new Committee on Energy and National Resources, which had succeeded the old Committee on Interior and Insular Affairs. The committee was initially intended to be temporary, but was made permanent in 1984. The committee tends to include senators from Western and Plains states, who have more American Indian constituents.
