The American Principles Project (APP) is a socially conservative 501(c)(4) political advocacy group founded in 2009 by Robert P. George, Jeff Bell, and Francis P.

[16] In 2011, APP sponsored a Republican presidential primary debate, called the Palmetto Freedom Forum, where panelists Jim DeMint, Steve King, and Robert P. George asked questions.

[17] Questions included Tea Party-related topics such as limited government, and candidates discussed upholding the Defense of Marriage Act and repealing other legislation.

"[27] APP is a member of the advisory board of Project 2025,[28] a collection of conservative and right-wing policy proposals from the Heritage Foundation to reshape the United States federal government and consolidate executive power should the Republican nominee win the 2024 presidential election.

[29] Terry Schilling, president of APP, advised the 2024 Republican National Convention platform committee on social and family issues.

[8] In 2020, the APP PAC spread disinformation that falsely claimed Joe Biden endorsed "sex change treatments" for children between age 8 and 10 years old.

[35][36] In 2022, the PAC spent $25,000 on commercials for a school board election in Polk County, Florida,[37] supporting candidates that were running on a parental rights platform.

[38] The commercials said that Democrats are "teaching trans ideology and anti-American critical race theory", but representatives for Polk County schools said those claims were false.

[7] In 2023, the APP PAC spent at least $796,000 on advertising in support of Daniel Kelly in the 2023 Wisconsin Supreme Court election, including ads with false information about school district policies regarding transgender youth.

[41] In 2023 the PAC also funded an attack ad against Kentucky governor Andy Beshear that said re-electing him would lead to the government removing trans-identifying children from families if parents asked them questions, which was not part of his platform.

[11] In 2023, APP policy director Jon Schweppe recommended that politicians pursue a federal ban on abortion with exceptions popular with voters, including rape, incest, or if the health or life of the mother is at risk.

[52] APP president Cannon criticized Trump's appointment of Betsy DeVos as United States secretary of education in 2016 because they did not think she was sufficiently opposed to Common Core.

[55] APP has funded political campaign ads that reflect the organization's opposition to civil rights protections for LGBTQ people.

[60][61] In the 2017 Virginia elections, the American Principles Project ran anti-transgender robocalls in the district of Democratic candidate Danica Roem, a former journalist who is a transgender woman.

[63][10] APP President Cannon said their polls showed that bathroom bills were less likely to motivate people to vote than potential unfairness in sports.

[5][6] In 2022 the American Principles PAC funded political advertisements in six states with claims about Democratic candidates, such as that they were "pushing dangerous transgender drugs and surgeries on kids" and "would destroy girls’ sports".

[41] Alfonso Aguilar, APP's Director of Hispanic Engagement, has spoken in favor of birthright citizenship[68] and against use of the term "anchor baby".

[83] It has lobbied for state and federal laws requiring age verification systems for pornographic websites, including the Kids Online Safety Act.

[88] In 2021, APP made a website and browser extension that provided information about nonprofits, think tanks, and academic institutions that take funding from Facebook, Google, Amazon, or Apple.
