At one time the King Airs were usually referred to as the "Beech King" aircraft. References to "the Government jet" rather than bothering to specify the type are another example of lazy journalism.
In fact, in my experience almost all aviation stories in the mainstream media should be treated with a healthy suspicion. They invariably contain inaccuracies - "a Hercules jet" is one of the regular ones, even when acompanied by photos showing the prominent propellors on the type.
