The Club for Growth is a fiscally conservative 501(c)(4) political organization, advocacy group, and political action committee (including its affiliated Club for Growth PAC and Club for Growth Action super PAC) in the United States. It is dedicated to promoting free-market policies, tax cuts, limited government, and economic freedom. The organization supports Republican and fiscally conservative candidates who align with these principles, particularly influencing Republican primaries by endorsing challengers to establishment figures and opposing tax increases. It engages in independent expenditures to defeat incumbents seen as insufficiently conservative on fiscal issues. The organization has been involved in high-profile races, such as endorsing Ted Cruz, and has faced investigations, including from Citizens for Responsibility and Ethics in Washington (CREW) over donor disclosures and activities. Major funders include Richard Uihlein and Farris Wilks, with ties to the Donors Capital Fund.
