Fox News contributors also directly discuss and promote their clients on-air. Take the cases of Fox Newsers Doug Schoen and Frank Luntz. On October 15, Schoen criticized the Democrats' strategy of making a campaign issue out of U.S Chamber of Commerce's funding sources. On October 6, Luntz applauded an ad by the Chamber and said the group has "done some of the best advertising across the country."
At no point did Fox News mention that Schoen and Luntz work for -- and presumably are paid by -- the Chamber. Luntz's website touts the Chamber as one of his clients.
The Schoen/Luntz situation isn't unique. In April of 2009, for instance, Fox News military analyst Tom McInerney -- last seen raising questions about Obama's birth certificate -- criticized the Obama administration's decision to procure only four more F-22 fighters. At no point did Fox News disclose that McInerney may have had a financial reason to be upset about the F-22 decision: he reportedly served as a consultant for the Northrop Grumman Corp., which is a major subcontractor on the F-22.
