There are a lot of sides to Washington, and from David Williams' vantage point the nation's capital looks far different than it does to folks in the financial industry.
Williams has served for 11 and a half years as the U.S. Postal Service's inspector general. He runs an agency of more than 1,000 people, who in turn oversee more than half a million Postal Service employees. So far this month, his office has published reports on topics like same-day mail delivery and the money that the post office collects from foreign countries when it delivers overseas mail to U.S. residents.
