(2-12-10) There are dozens of federal agencies in Washington, D.C., and dozens of men and women running them, but it's hard to imagine that any of these civil servants has a Tom Sawyer streak wider than Rocco Landesman's. His CV includes the kind of grown-up adventures that his fellow (if fictional) Missourian might envy. He started and ran a multimillion-dollar investment fund, owned and bet on racehorses, and faced the most ludicrous odds of all by becoming a Broadway producer. Nor did this exhaust his energies. He once came close to buying the Cincinnati Reds.
