Ken Silverstein at Harpers.org provides more info on Shirlington Limousine and their government contracts. Shirlington received a number of government contracts that total $25 million. Also, Silverstein reports that, “The limo company does business under at least four different names; in addition, the office addresses listed on its business filings regularly change. A number of those office addresses are actually at residential buildings or business suites, and calls to the listed phone numbers are taken by an answering service.” This sounds a lot like how Brent Wilkes’ operated – the creation of shell companies, front companies with no address and voice recordings.
