Yes, there is a connection.

Freshman Sen. David Vitter apologized last night after documents released by the D.C. Madam, Deborah Jane Palfrey, revealed that he had patronized her high-end, fantasy escort service at least once before he was elected to the Senate.

Recall that Vitter was among the first Republicans to endorse the presidential candidacy of Rudy Giuliani and has come to serve as one of Giuliani's chief liaisons to social conservatives. He is also Giuliani's chief whip in the Senate and serves as the Southern regional chairman of his campaign. This revelation won't break up that relationship, but it does cast doubt on Mr. Vitter's ability to be a messenger between Giuliani and his critics.
