Editing White House Staff (section)

== Mission ==
The issues that confront the United States at any one time cannot be dealt with by the president alone, and therefore the president draws on the expertise of others in the administration and even within an administration as one chief of staff may differ from a predecessor or successor.

While chiefs of staff may differ in the degree of policy advice they provide a president, they are the managers of the White House staff system. At least in theory, they are the coordinators bringing the pieces together; they are the tone-setters and disciplinarians making for good organizational order, and often act as the gatekeeper for the president, overseeing every person, document and communication that goes to the president.
