History

The committee has its roots in the Committee on Commerce and Manufacturers, which served as a standing committee in the early-1800s. This committee was split in two in the 1820s and remained in this configuration until the Legislative Reorganization Act of 1946. Under the LRA, the number of standing committees was dramatically decreased to increase congressional efficiency and increase institutional strength. As a result, the Committee on Commerce, the Committee on Manufactures, the Committee on Interstate Commerce, and the Committee on Interoceanic Canals were combined into the United States Senate Committee on Interstate and Foreign Commerce. In 1977, as a part of widespread committee reorganization, the committee was renamed the Committee on Commerce, Science, and Transportation and given additional oversight jurisdiction over nonmilitary aeronautical and space sciences, including the National Aeronautics and Space Administration (NASA).

The original progenitors of this committee were:

• United States Senate Committee on Commerce and Manufactures (1816–1825)
• United States Senate Committee on Commerce (1825–1946, 1961–1977)
• United States Senate Committee on Manufactures (1825–1855, 1864–1946)
• United States Senate Committee on Interstate Commerce (1885–1946)
• United States Senate Committee on Interoceanic Canals (1899–1946)
• United States Senate Committee on Interstate and Foreign Commerce (1946–1961)
• United States Senate Committee on Aeronautical and Space Sciences (1958–1977)

Notes

1. At the beginning of the 107th Congress in January 2001 the Senate was evenly divided. With a Democratic president and vice president still serving until January 20, the Democratic vice president was available to break a tie, and the Democrats thus controlled the Senate for 17 days, from January 3 to January 20. On January 3 the Senate adopted S. Res. 7 designating Democratic senators as committee chairmen to serve during this period and Republican chairmen to serve effective at noon on January 20, 2001.
2. On June 6, 2001, the Democrats took control of the Senate after Senator James Jeffords (VT) changed from the Republican Party to Independent and announced that he would caucus with the Democrats.
3. Kyrsten Sinema is formally an independent but caucuses with the Democrats.
