In recent years, the U.S. Supreme Court has repeatedly relied on history to decide major questions of constitutional law. In response to this trend, in 2023 the Brennan Center for Justice created a Historians Council on the Constitution, made up of leading constitutional and legal historians from across the nation. Jonathan Gienapp was among the first to join and has been an active member since, including helping to write several historians’ amicus briefs for the Supreme Court, which are listed below along with prior briefs he signed.

Gienapp provided expert testimony in Dinner Table Action v. Schneider, litigation challenging an approved 2024 Maine ballot initiative to limit SuperPACs. Gienapp’s declaration focused on the original meaning and understanding of the First Amendment as it might relate to campaign finance regulations, detailing how the Founding generation thought about constitutional rights and their enforcement.
