The Lincoln Project is an American political action committee founded on December 17, 2019, by current and former Republicans, including prominent strategists George Conway, Steve Schmidt, John Weaver, Rick Wilson, Reed Galen, Jennifer Horn, Mike Madrid, and Ron Steslow, who oppose Donald Trump and Trumpism. Operating as a hybrid PAC and 501(c)(4) with addresses in Dallas, TX, and Washington, DC, the group rapidly gained prominence through aggressive, viral anti-Trump advertising campaigns, social media efforts, and endorsements of Joe Biden in April 2020 and Kamala Harris in 2024. It spent over $15 million on ads during the 2020 election cycle, raised approximately $78 million by November 2020, and founded The Union coalition with 62,000 volunteers for 2020 efforts. Senior advisors have included Rachel Bitecofer, Tara Setmayer, and others; the current executive director is Sarah Lenti. Active on social media (@ProjectLincoln on X, Instagram, etc.), it positions itself as a pro-democracy organization with a broad coalition beyond Republicans and continues to criticize Trump post-election. The organization has faced significant controversies, including 2021 allegations of sexual misconduct against co-founder John Weaver, who reportedly harassed young men, with leadership accused of prior knowledge, leading to Weaver's departure, Steve Schmidt's resignation, and donor backlash. Financial scrutiny arose over payments to vendors linked to leaders like Reed Galen and opaque 'dark money' arrangements via Project Yellowstone. Other incidents include a 2021 tiki torch stunt mimicking Charlottesville to criticize Glenn Youngkin, which was widely condemned, and a threatened defamation lawsuit against Rudy Giuliani for falsely accusing the group of plotting January 6.
