Justice Department chief information officer Luke McCormack is heading back to the Homeland Security Department to serve as CIO. He replaces Richard Spires, who left the position in May. President Barack Obama announced his decision to appoint McCormack last night. McCormack previously served as CIO for Immigration and Customs Enforcement and acting director for Customs and Border Patrol’s Infrastructure Services Division. He’s also expected to continue his role leading the information security and identity management committee at the federal CIO Council.
