Meet Chris Ullman, D.C.’s universally admired whistler

The four-time international whistling champion is a partner in “The Carlyle Group,” an investment firm. He’s been in Washington for 30 years, working at the highest levels in both private and public sectors. Along the way he has earned a reputation as perhaps D.C.’s only universally admired whistle blower. He speaks with Steve Hartman “On the Road” on CBS News.
