Lewis was named executive vice president of corporate communications at the top-rated cable-news network in 2006, and helped shape the network’s perception among the media. He has also been known as an adviser to the network’s chairman and chief executive, Roger Ailes.
Lewis could not be reached for immediate comment. News of his dismissal was reported previously by The Hollywood Reporter.
“After an extensive internal investigation of Brian Lewis’ conduct by Fox News, it was determined that he should be terminated for cause, specifically for issues relating to financial irregularities, as well as for multiple, material and significant breaches of his employment contract,” the company said in a statement. “He was terminated for cause on July 25.”
Lewis’s name has been removed as a contact on the Fox News web site’s press section.
