Philip Wallach

Philip Wallach is a senior fellow at the American Enterprise Institute who studies America's separation of powers, with a focus on the relationship between Congress and the administrative state. His 2023 book Why Congress argues that the legislative branch sits at the heart of the constitutional system and warns that its self-imposed irrelevance is letting the executive and the courts rush into the vacuum. A Princeton-trained scholar and a fixture in debates over regulatory policy, DOGE, and congressional reform, he writes for outlets ranging from National Affairs to the Wall Street Journal and the Washington Post.
