Jack Theis represents clients in times of crisis. As a former Associate White House Counsel, Department of Justice trial lawyer, and civil litigator, he brings a wealth of public and private sector experience to companies and industry leaders facing complex challenges. Known for keeping an even keel in high-stress situations, Jack brings a practical approach to complicated problems. He counsels clients facing individual and class action litigation, government investigations, and multidimensional crises involving legal and reputational risks. Jack has experience handling matters involving cybersecurity and data privacy, internal and government investigations, antitrust and competition law, constitutional challenges, and other legal risks and challenges.

Jack joined RSHC after serving as Special Assistant and Associate Counsel to President Obama. At the White House, he advised senior administration officials on oversight investigations and high-profile litigation, and worked closely with officials at the Department of Homeland Security, the Department of Justice, and the Office of Management and Budget. Jack represented the White House in congressional investigations, managed attorney fact-gathering teams in internal investigations, prepared witnesses for appearances at congressional hearings and interviews, and counseled clients on developing strategies to respond to requests for information.

During his time as a Trial Attorney at the Federal Programs Branch of the Department of Justice, Jack represented Executive Branch agencies in high-stakes constitutional and regulatory litigation in federal courts across the country. He defended some of the Administration’s most contentious and sensitive policies related to national security, cybersecurity, and federal grant programs. He counseled federal agencies in litigation stemming from two high-profile breaches of government data, including in a multidistrict litigation involving a data breach at the Office of Personnel Management affecting over 21 million people. In 2016, he received a Special Commendation for Outstanding Service in the Civil Division.

Earlier in his career, Jack represented corporate clients in complex commercial litigation matters at two Chicago law firms with a focus on antitrust and class actions.

Born and raised in Chicago, he also cares deeply about serving the community, and has served on the Legal Assistance Foundation Young Professionals Board, the Board of Directors of the Chicago Chapter of the American Constitution Society, and as a National Security Fellow with the Truman National Security Project.
