Clark has extensive experience in government service and private practice. He most recently served President Trump at the White House as Acting Administrator of the Office of Information and Regulatory Affairs at the Office of Management and Budget. In the past, he had also served as the Assistant Attorney General for the Environment and Natural Resources Division and the Acting Assistant Attorney General for the Civil Division. His credentials extend well beyond these three high-ranking political appointments. In addition to his government service, Clark was a “BigLaw” partner in Washington, D.C. and occupied important national leadership posts, not just in a conservative legal organization, but also held an elected office at the American Bar Association.
