Alliance Defending Freedom (ADF, formerly Alliance Defense Fund) is an American conservative Christian nonprofit advocacy[citation needed] group. ADF is headquartered in Scottsdale, Arizona. It also has four branch offices located in Folsom, California; Washington, D.C.; Lawrenceville, Georgia; and New York.[5]
Because of its budget, caseload, and network of allied attorneys, ADF is seen as the most organized and influential Christian legal interest group in the country.[6] As of October 2018, ADF attorneys had argued nine cases before the Supreme Court and won all of them. The Supreme Court cases involved issues impacting religious freedom, including a challenge to the Affordable Care Act, equal access for an after-school club, funding for student religious publications, and prayers before town meetings.
