Some of the most influential people in American government are those who advise the president. Although they serve in nonelected positions, these advisors have the ability to shape and influence both domestic and foreign policy. Presidential advisors come in three categories: cabinet members, White House staff, and nongovernmental advisors. In this chapter, you'll learn about the cabinet, White House staff, and others who have the president's ear. The next chapter will examine the rest of the federal bureaucracy.
