Tom LoBianco, writing for the Associated Press, has a good piece of investigative journalism which takes a look at the relationship of former Tony Bennett chief of staff, Todd Huston, with his once and future employer, Cisco Systems, and the Indiana Department of Education.
It looks like Huston left Cisco to come work with Bennett at the Department of Education, maintained a close relationship with the Cisco people while he was at the IDOE and arranged contacts between Cisco sales people and the Department of Education, then left the IDOE to go back to Cisco while still providing education policy advice to Bennett and facilitating contacts between Cisco sales people and the IDOE.
The story has a sort of Mitch Roob feel to it.
