The way personnel spin through Washington's infamous revolving door between the Pentagon and the arms industry is nothing new. That door, however, is moving ever faster with the appointment of Patrick Shanahan, who spent 30 years at Boeing, the Pentagon's second largest contractor, as the Trump administration's acting secretary of defense.
Shanahan had previously been deputy secretary of defense, a typical position in recent years for someone with a significant arms industry background. William Lynn, President Obama's first deputy secretary of defense, had been a Raytheon lobbyist. Ashton Carter, his successor, was a consultant for the same company. One of President George W. Bush's deputies, Gordon England, had been president of the General Dynamics Fort Worth Aircraft Company (later sold to Lockheed Martin).
