As a member of the Government Investigations & White Collar Practice, Clark K. Ervin helps clients under investigation, or facing the prospect of investigation, by federal Offices of Inspector General, to craft, coordinate and implement strategic defenses. An integral member of the firm’s Homeland Security, Defense and Technology Transfer team, as well as our International Public Policy Practice, Clark also provides invaluable counsel to clients, both corporations and foreign sovereigns, on issues of national security and foreign policy.

    Having served as Inspector General of three federal agencies during the administration of President George W. Bush, Clark brings extensive experience and notable expertise to the firm’s Government Investigations & White Collar Practice. From 2003 to 2004, he served as the very first Inspector General of the Department of Homeland Security (DHS), and from 2001 to 2002, as the Inspector General of the Department of State (State) and, simultaneously, the Broadcasting Board of Governors (BBG), the global media arm of the US government.

    In addition to counseling clients facing Inspector General-led investigations, Clark’s work focuses on other executive branch, congressional and internal corporate investigations, and he plays an active role in the firm’s dealings with State Attorneys General, applying knowledge gained while he served the State of Texas as Assistant Secretary of State and a Deputy Attorney General during then Governor George W. Bush’s administration. In this capacity, he represents clients being investigated by State Attorneys General and he also advocates clients’ policy positions to State Attorneys General. Finally, drawing on his experience at State and DHS, Clark counsels clients on cybersecurity matters and immigration-related matters, including the EB-5 Program.

    Clark also has considerable expertise in monitorships. In May 2016, the US Department of Education approved Zenith Education Group’s (Zenith) selection of the firm, with Clark leading the team, as the Monitor with respect to certain provisions the department required Zenith to comply with as a condition of its approval of Zenith’s acquisition of some formerly for-profit colleges owned by the now defunct Corinthian Colleges. In July 2016, the US Department of Justice and the City of Ferguson selected the firm, with Clark leading the team, as the Monitor with respect to the Ferguson Police Department’s and the city’s municipal court system’s compliance with the terms of a consent decree. He also counsels companies on compliance-related matters.

    In 2008, Clark served as the co-chairman of then President-elect Barack Obama’s Transition Team for DHS, adding to the experience he gained while previously serving as the department’s first Inspector General. From its inception in 2008 to its expiration in September 2011, Clark, an appointee of then House Speaker Nancy Pelosi, served as one of the eight members of the independent, bipartisan congressional Commission on Wartime Contracting in Iraq and Afghanistan.

    Clark’s government experience is complemented by his policy expertise. Since leaving DHS in 2004, Clark has been affiliated with the Aspen Institute, where he founded and chairs the Homeland Security Program. In this capacity, Clark convenes policymakers and thought leaders in homeland security and counterterrorism with a view to helping shape the policy debate.His signature program at the Institute, the annual Aspen Security Forum, brings top-level present and former government officials, industry and thought leaders, and nationally noted print and broadcast journalists to Aspen each summer to discuss and debate the key issues of the day in the fields of national security. Clark also founded and serves as the chairman of the Aspen Homeland Security Group, a bipartisan group of former government officials and policy experts that provides informal advice and counsel to the Homeland Security Secretary and other national security-related policymakers.

    Formerly an on-air analyst and contributor at CNN, Clark still appears as a guest commentator on television and radio networks, and is often cited as an expert by major national and international publications, including The Wall Street Journal, Time and The Economist. His opinion pieces have appeared in The New York Times and The Washington Post. Clark’s book on homeland security – Open Target: Where America is Vulnerable to Attack – was published by the St. Martin’s Press imprint, Palgrave Macmillan, in 2006.
