Public Biography
Arthur Penniman is the chief counsel of the United States House Judiciary Committee, a position he has held since 2023. He oversees the committee’s legal staff and advises members on matters of constitutional law, legislative procedure, and enforcement authority, including contempt of Congress citations.
Mr. Penniman holds a J.D. from Yale Law School and a bachelor’s degree in political science from Amherst College. He clerked for Judge Patricia Millett on the U.S. Court of Appeals for the D.C. Circuit before joining the Congressional Research Service, where he spent eight years as a specialist in American constitutional law. He joined the Judiciary Committee staff in 2017 and was elevated to chief counsel six years later.
He is the author of a widely cited CRS report, “Contempt of Congress: A Brief History and Procedural Overview” (2019), which has been updated three times and which he has described as “a document I hoped would remain of purely academic interest.”
In April 2026, Mr. Penniman authored a nine-page internal memorandum advising the committee that its contempt citation against former White House policy adviser Dale Whitford was “procedurally untenable” in light of national polling data showing that contempt of Congress is the prevailing position of the American electorate. The memorandum introduced the phrase “approval environment” into the committee’s procedural vocabulary, a contribution he has not publicly commented on.
