My response on an earlier thread. From Wikipedia:
In 2011, Richardson joined the boards of APCO Worldwide company Global Political Strategies as chairman, the World Resources Institute, the National Institute for Civil Discourse at the University of Arizona, and Abengoa (international advisory board). He was also appointed as a special envoy for the Organization of American States.Given his stature (or more honestly his notoriety), he no doubt is reeling in the dough from speaking appearances like his recent stint at Harvard.
