Before joining the White House, Jason served as part of the senior leadership team at the U.S. Department of Justice, where he was Counselor to the Attorney General and Counselor and Chief of Staff to the Associate Attorney General.

Previously, Jason was an award-winning federal prosecutor and accomplished appellate attorney. He worked as an appellate Assistant United States Attorney, a deputy Ohio solicitor general, and an appellate associate at Gibson, Dunn & Crutcher. In these various roles, he handled dozens of civil and criminal appeals (primarily in the U.S. Supreme Court, the U.S. Court of Appeals for the Sixth Circuit, and the Ohio Supreme Court) and presented eighteen oral arguments (in the Sixth Circuit, the D.C. Circuit, the Ohio Supreme Court, and federal district courts in Ohio and D.C.).
Jason has also worked on the confirmations of several of President Donald J. Trump’s Executive Branch and judicial nominees, including serving on the U.S. Senate Committee on the Judiciary as Special Counsel to Senator Ted Cruz for the confirmation of Justice Amy Coney Barrett.
