Hill committee

The Hill committees are the common name for five political party committees, four of which are controlled by the Republican and Democratic caucuses in each house of the United States Congress, which work to elect members of their own party to Congress (located on Capitol Hill, the source of the name).

They are the:
*Democratic Congressional Campaign Committee (DCCC, or "D-triple-C")
*National Republican Congressional Committee (NRCC)
*Democratic Senatorial Campaign Committee (DSCC)
*National Republican Senatorial Committee (NRSC)
*Libertarian National Congressional Committee (LNCC)

Each committee works to recruit, assist, and support candidates of their own party, for their own chamber, in targeted races around the country. The committees contribute directly to candidates' campaigns, while also lending expertise, providing campaign-related services, and making independent expenditures. They raise funds at the national level from donors whose focus is on Congress as a whole, rather than individual campaigns.

Hill committee chairs are incumbents chosen each election cycle by the leadership of their caucus. Typically they are proven fundraisers with national political ambitions who are not facing competitive re-election campaigns. The committees are run on a day-to-day basis by a professional staff with campaign experience.
