United States Senator, Utah
Elected in 2010 as Utah's 16th Senator, Mike Lee has spent his career defending the basic liberties of Americans and Utahns as a tireless advocate for our founding constitutional principles.
Senator Lee acquired a deep respect for the Constitution early on. His father, Rex Lee, who served as the Solicitor General under President Ronald Reagan, would often discuss varied aspects of judicial and constitutional doctrine around the kitchen table, from Due Process to the uses of Executive Plenary Power. He attended most of his father's arguments before the U.S. Supreme Court, giving him a unique, hands-on experience and understanding of government up close.
Lee graduated from Brigham Young University with a Bachelor of Science in Political Science, and served as BYU's Student Body President in his senior year. He graduated from BYU's Law School in 1997 and went on to serve as law clerk to Judge Dee Benson of the U.S. District Court for the District of Utah, and then with future Supreme Court Justice Judge Samuel A. Alito, Jr. on the U.S. Court of Appeals for the Third Circuit.
Lee spent several years as an attorney with the law firm Sidley & Austin specializing in appellate and Supreme Court litigation, and then served as an Assistant U.S. Attorney in Salt Lake City arguing cases before the U.S. Court of Appeals for the Tenth Circuit.
Lee served the state of Utah as Governor Jon Huntsman's General Counsel and was later honored to reunite with Justice Alito, now on the Supreme Court, for a one-year clerkship. He returned to private practice in 2007.
Throughout his career, Lee earned a reputation as an outstanding practitioner of the law based on his sound judgment, abilities in the courtroom, and thorough understanding of the Constitution.
Today, Lee fights to preserve America's proud founding document in the United States Senate. He advocates efforts to support constitutionally limited government, fiscal responsibility, individual liberty, and economic prosperity.
Lee is a member of the Judiciary Committee, and serves as Chairman of the Antitrust, Competition Policy and Consumer Rights Subcommittee protecting business competition and personal freedom.
He also oversees issues critical to Utah as the Chairman of the Water and Power Subcommittee of the Energy and Natural Resources Committee. He serves on the Commerce Committee and the Joint Economic Committee, as well.
In the 114th Congress, Lee also began his tenure as Chairman of the Senate Steering Committee, where he works with his Republican colleagues in the Senate to introduce bold and innovative solutions to issues facing the American people.
Lee and his wife Sharon live in Alpine, Utah, with their three children. He is a member of The Church of Jesus Christ of Latter-day Saints and served a two-year mission for the Church in the Texas Rio Grande Valley.

Judge, U.S. Court of Appeals for the Third Circuit
Hon. Jennifer Mascott served as Associate Professor of Law and Director of the Separation of Powers Institute at The Catholic University of America’s Columbus School of Law before her appointment to the federal bench. On July 16, 2025, President Donald J. Trump nominated her to the U.S. Court of Appeals for the Third Circuit (Delaware), and she was confirmed on October 9, 2025.
Prior to her confirmation, Judge Mascott wrote extensively in administrative and constitutional law, statutory interpretation, and the separation of powers. Her scholarship—published in leading journals including the Stanford Law Review, Notre Dame Law Review, and Supreme Court Review—was cited by the U.S. Supreme Court and multiple federal courts. She also contributed Supreme Court commentary for NBC Universal.
Before joining Catholic Law, she was an Assistant Professor and Co-Director of The C. Boyden Gray Center at George Mason University’s Antonin Scalia Law School. In 2022 she became co-author of Beermann, Cass & Diver’s Administrative Law: Cases and Materials (9th ed.).

William K. Townsend Professor of Law, Yale Law School
Nicholas R. Parrillo is Townsend Professor of Law at Yale, with a secondary appointment as Professor of History. His research and teaching focus on administrative law and government bureaucracy and extend to legal history, remedies, and legislation. He has received the ABA’s award for the year’s best scholarship in administrative law and the Law and Society Association’s Hurst Prize for the year’s best book in legal history.
Parrillo’s Yale Law Journal article finding new originalist evidence of broad congressional delegations to agencies was discussed in the Solicitor General’s winning brief in the Supreme Court’s latest nondelegation case and in the en banc 5th Circuit opinion in that case. His Harvard Law Review article on how the judiciary handles the federal government’s disobedience to court orders has been discussed in The Washington Post, The Wall Street Journal, and The New York Times. Parrillo also authored a study that provided the empirical basis for best practices adopted by the Administrative Conference of the United States (ACUS) on the federal government’s ubiquitous but controversial use of guidance documents. Peer scholars at Jotwell, in selecting the “best new scholarship” in law, selected each of these three publications (one of them twice). Parrillo’s most recent article, invited for GW’s annual administrative law issue, reveals and analyzes dramatic variation among industries in their willingness to sue their federal health-and-safety regulators.
Parrillo has testified before Congress, been quoted by the Supreme Court, is a senior fellow of ACUS, and has been an instructor at the New York Historical Society’s graduate institute and an invited speaker before the 2nd Circuit Judicial Conference, the U.S. Department of Justice (in 2019 and again in 2024), the ACLU’s national legal staff, and the Federalist Society’s national convention (two times).

In 2023 she received the Justice Joseph Story Award for excellence in scholarship, teaching, and advancing the rule of law.
Judge Mascott also served as a Council Member of the ABA’s Administrative Law Section and as a Public Member of the Administrative Conference of the United States. She frequently testified before Congress on executive power, regulatory reform, and judicial jurisdiction, and participated in multiple Supreme Court confirmation hearings.
From 2019 to 2021, she took leave from academia to serve as Deputy Assistant Attorney General in the Department of Justice’s Office of Legal Counsel and later as Associate Deputy Attorney General, where she argued federal cases and assisted with Justice Amy Coney Barrett’s confirmation. Earlier in her career, she clerked for Justice Clarence Thomas and for then-Judge Brett M. Kavanaugh on the D.C. Circuit.
Judge Mascott earned her J.D. summa cum laude from the George Washington University Law School and her B.A. from the same institution.
William K. Townsend Professor of Law, Yale Law School
Nicholas R. Parrillo is Townsend Professor of Law at Yale, with a secondary appointment as Professor of History. His research and teaching focus on administrative law and government bureaucracy and extend to legal history, remedies, and legislation. He has received the ABA’s award for the year’s best scholarship in administrative law and the Law and Society Association’s Hurst Prize for the year’s best book in legal history.
Parrillo’s Yale Law Journal article finding new originalist evidence of broad congressional delegations to agencies was discussed in the Solicitor General’s winning brief in the Supreme Court’s latest nondelegation case and in the en banc 5th Circuit opinion in that case. His Harvard Law Review article on how the judiciary handles the federal government’s disobedience to court orders has been discussed in The Washington Post, The Wall Street Journal, and The New York Times. Parrillo also authored a study that provided the empirical basis for best practices adopted by the Administrative Conference of the United States (ACUS) on the federal government’s ubiquitous but controversial use of guidance documents. Peer scholars at Jotwell, in selecting the “best new scholarship” in law, selected each of these three publications (one of them twice). Parrillo’s most recent article, invited for GW’s annual administrative law issue, reveals and analyzes dramatic variation among industries in their willingness to sue their federal health-and-safety regulators.
Parrillo has testified before Congress, been quoted by the Supreme Court, is a senior fellow of ACUS, and has been an instructor at the New York Historical Society’s graduate institute and an invited speaker before the 2nd Circuit Judicial Conference, the U.S. Department of Justice (in 2019 and again in 2024), the ACLU’s national legal staff, and the Federalist Society’s national convention (two times). He is a recipient of the Law School’s annual teaching award.

Harvie Wilkinson III of the U.S. Court of Appeals for the Fourth Circuit and, in the 2001 October Term, as law clerk to Justice Clarence Thomas of the U.S. Supreme Court.

In 2002, she joined the international arbitration group of Clifford Chance LLP in London, England.

In July 2017, she was appointed to serve as the Administrator of the Office of Information and Regulatory Affairs in the Office of Management Budget.
