David Corn has a Vitter scoop:

Imagine this scenario: A young congressional aide who moonlights for an escort service receives a call from her madam. The woman who owns the service asks her to meet a customer at a certain spot and time. When the aide/escort arrives, she sees that the client is a member of Congress and sits on the very same committee where she works. Embarrassing? Uncomfortable? A potential scandal? They now each know a big secret about the other. She knows he is using an escort service. He knows she is working for that same service. What do they do? Is his--or her--political career in peril?

The records of Deborah Jeane Palfrey, a.k.a. the DC Madam, suggest that Republican Senator David Vitter came close to experiencing such an awkward moment when he served in the House of Representatives. These phone records indicate that Palfrey may have set Vitter up with an escort who was a staffer for a congressional committee that included Vitter as a member. But if the two did meet for an escort experience, Vitter escaped being found out by his (indirect) subordinate.
