An example of the revolving door occurs when

A) a former secretary of state writes his memoirs.
B) a former chief of staff for the president hosts a news talk show.
C) a former employee of one administration is hired by the next administration.
D) the press reports on political events without naming specific people.

The term "revolving door" refers to the movement of individuals between roles as legislators and regulators and the industries affected by the legislation and regulation, often creating a conflict of interest. Choice B, where a former chief of staff for the president hosts a news talk show, exemplifies this as it involves a transition from a political role to a media role, potentially influencing public opinion or policy through media.
