Senate Homeland Security will be an experienced committee this year. The Senate Committee on Homeland Security and Governmental Affairs is the Senate’s primary oversight committee with broad jurisdiction over government operations generally and the Department of Homeland Security in particular. Its primary responsibilities are to study the efficiency, economy, and effectiveness of all agencies and departments of the federal government; evaluate the effects of laws enacted to reorganize the legislative and executive branches of government; and study the intergovernmental relationships between the U.S. and states and municipalities, and between the U.S. and international organizations of which the U.S. is a member.
