Klein was D.C.'s transportation director for two years, during which time he set up the city's bike sharing system, launched a new bus service and started building a streetcar.
Hilkevitch talks to Klein about his boss' goals for Chicago:
"He wants to create a really livable, cutting-edge city, and he sees it more as a driver for economic growth than anything else. He's one of the only leaders in America that gets that."
