Overview

Americans for Prosperity (AFP) is a United States-based libertarian-conservative political advocacy organization founded in 2004 after an internal split within Citizens for a Sound Economy. The organization was established with financial support from Charles Koch and David H. Koch and became closely associated with the Koch family's broader political and philanthropic network, although Koch Industries has stated that its companies do not direct AFP's activities. AFP operates alongside the Americans for Prosperity Foundation, a related 501(c)(3) charitable organization, and Americans for Prosperity Action, a super PAC that supports conservative candidates. AFP describes its mission in terms of mobilizing citizens around policies intended to reduce regulation, limit government spending, lower taxes, expand economic opportunity, and restrain what it regards as special-interest influence. Its policy agenda has included opposition to the Affordable Care Act and Medicaid expansion, resistance to federal climate and energy regulations, support for expanded domestic energy production, opposition to increases in the federal minimum wage, and advocacy for right-to-work laws and restrictions on public-sector collective bargaining. The organization has also supported reductions in public-sector benefits and pensions and criticized government spending on programs including Social Security, Medicare, and Medicaid. The group became nationally prominent after Barack Obama's 2009 inauguration. AFP helped provide organizational infrastructure, speakers, permits, training, messaging, and communications for the emerging Tea Party movement. It participated in protests against the 2009 economic stimulus legislation and helped organize Tax Day and September 12 demonstrations. During the 2010 midterm elections, it supported voter-registration drives, canvassing, phone banking, activist training, bus tours, and extensive advertising. Its activities were widely viewed as contributing to the Republican takeover of the U.S. House of Representatives. AFP later became an important force in state-level policy campaigns, particularly in Wisconsin, where it supported Governor Scott Walker's agenda to reduce public spending and limit public-sector collective bargaining. The organization has operated as a tax-exempt 501(c)(4) social-welfare nonprofit. This status permits advocacy and some political activity but does not require the same public disclosure of donors as a political action committee. AFP's ability to spend substantial sums on political communications while keeping many contributors confidential has made it a prominent example in debates over nonprofit political spending and so-called dark money. Critics, including campaign-finance watchdogs and Democratic politicians, have questioned the transparency and legal boundaries of its activity, while AFP has defended donor privacy and argued that its work is educational and protected by constitutional principles. AFP expanded from a relatively small organization into a national network with state chapters, professional staff, grassroots volunteers, policy campaigns, and election operations. It registered to lobby in 2014 and has participated in national, state, and local political contests without formally functioning as a political party. Tim Phillips led AFP and its foundation for much of the organization's period of rapid growth, serving as president from 2006 until 2021. In 2023, Wyoming became the organization's thirty-sixth state chapter according to the referenced account. AFP remains active as a conservative policy and grassroots advocacy network, but detailed current leadership, staffing, donor composition, and financial information are not established by the supplied materials.

History

Americans for Prosperity emerged in 2004 from the division of Citizens for a Sound Economy, a conservative advocacy organization whose internal rivalries produced both AFP and FreedomWorks. Charles Koch and David H. Koch provided early financial support. AFP was created as an educational and grassroots organization intended to explain economic policy and encourage citizens to participate in public-policy debates. Its companion foundation was structured as a charitable 501(c)(3) organization, while AFP operated as a 501(c)(4) social-welfare nonprofit. Nancy Pfotenhauer led the organization during its first years, and Tim Phillips joined the Koch-supported effort in 2005 before becoming president in 2006. Under Phillips, AFP developed a national network of state chapters, staff, volunteers, policy specialists, and communications operations. Its stated priorities centered on lower taxes, reduced regulation, spending restraint, free markets, entrepreneurship, and limits on government intervention. The organization frequently framed its work as a counterweight to labor unions and progressive activist groups. AFP's national profile rose sharply after 2009. It helped turn the Tea Party movement's spontaneous protests into a more durable political force by arranging event logistics, recruiting speakers, creating websites and talking points, training activists, and organizing rallies. It opposed the Obama administration's economic stimulus, the Affordable Care Act, Medicaid expansion, and proposed cap-and-trade legislation. AFP's environmental and energy positions included opposition to climate regulations and support for expanded domestic energy production. The organization became a major participant in the 2010 midterm elections. It financed advertising and field operations, supported voter-registration efforts, supplied activists with campaign materials, and organized a bus tour called “November is Coming.” Its spending and organizational reach helped Republican candidates and contributed to the party's House majority. AFP subsequently applied similar methods to state campaigns, most visibly in Wisconsin, where it supported Scott Walker's efforts to reduce public-sector benefits and restrict collective bargaining. It also advocated right-to-work laws and opposed raising the federal minimum wage. AFP's structure and funding have generated continuing controversy. It shares personnel and offices with the AFP Foundation, but the two entities are subject to different tax rules. AFP may engage in some political activity without publicly identifying all donors, whereas the foundation is more restricted in political activity and donations to it are generally tax deductible. Critics have argued that this structure enables substantial undisclosed political spending. AFP and its supporters have defended confidentiality by citing donor privacy and the risk of harassment. Complaints were also filed with the Internal Revenue Service alleging that foundation-related advertising violated nonprofit restrictions; AFP rejected those claims. After the 2010 Citizens United decision, AFP became part of the expanding network of nonprofit organizations involved in anonymous election spending. In 2014 it registered to lobby and was described by multiple news organizations as operating in ways comparable to a national political party, despite its nonprofit status. Americans for Prosperity Action later added a super-PAC vehicle to the network. Tim Phillips left the presidency in 2021. The organization continued expanding its state presence, reaching a reported thirty-six chapters with the addition of Wyoming in 2023. Current operational details and leadership beyond the supplied historical material remain uncertain.
