I have no opinion about whether he’s a good fellow or not, but this is one of the most absurd reasons for a forced resignation from government I’ve seen: “State Department official resigns over ‘D.C. madam’.”
UPDATE: Well, I do see a good reason now:
As a top official overseeing global AIDS funding to other countries, Tobias was responsible for enforcing a U.S. policy, enacted during the Bush administration, that requires recipients to swear they oppose prostitution and sex trafficking. USAID adopted a similar policy in 2004.
