For his interview with Judge Douglas Ginsburg at Scalia Law School, Deputy Attorney General Rod J. Rosenstein did not say much about the investigation. He talked about his career and a bit about his personal life. He did confirm his reason for appointing Robert Mueller as a special counsel. No one can do the job better than Mueller. He also sees his responsibility in broader obligations, and not about his reputation or party affiliation. He is doing the right thing and I thank him for that.
