Oregon Attorney General John Kroger is on his way to become the next president of Reed College. I'd call him my "former colleague" except that we haven't really been colleagues; rather, I'm more like his replacement here at Lewis & Clark, having inherited the core criminal courses he taught, as well as his office.
The move from being the top law enforcement officer in the jurisdiction to college president may seem unusual, but there is some precedent for this kind of move. Back when I was clerking in San Diego for a federal judge, the U.S. Attorney there was Alan Bersin (coincidentally, a former partner at Munger Tolles & Olson, the law firm that I would later join as an associate). In 1998, Bersin became the Superintendent for the San Diego Unified School District, and then later, the California Education Secretary.
