The Journal also suggested that other lawmakers might be implicated. I've learned from a well-connected source that those under intense scrutiny by the FBI are current and former lawmakers on Defense and Intelligence comittees—including one person who now holds a powerful intelligence post.

It gets even more interesting: the man who has been identified as the CEO of Shirlington has a 62-page rap sheet (I recently obtained a copy) that runs from at least 1979 through 1989 and lists charges of petit larceny, robbery, receiving stolen goods, assault, and more. Curiously—or perhaps not so curiously given the company's connections—Shirlington Limousine is also a Department of Homeland Security contractor; according to the Washington Post, last fall it won a $21.2 million contract for shuttle services and transportation support. (I tried to contact Shirlington but was unable to get past their answering service.)
