Chevron Corporation on Thursday announced the retirement of Charles James as executive vice president and a member of the company’s five-person executive committee. James held the post of general counsel from 2003 until last year. Before that, he served as the Justice Department‘s antitrust chief under both former President Bush and George H.W. Bush, and as a partner at Jones, Day, Reavis & Pogue.

According to Chevron’s statement, James will join the adjunct faculty at Arizona State University College of Law, and devote himself to philanthropic activities. Never shy of controversy, James offered Corporate Counsel his unedited thoughts on national security review, corruption, human rights, climate change, and running a legal department.
