While the President of the United States is often seen as the most powerful person in the world, the vastness of the Federal government is too much for just one person to oversee. The president needs someone to control events, run the White House, respond to challenges and handle emergencies. That person is the Chief of Staff. Chris Whipple, author of The Gatekeepers: How the White House Chiefs of Staff Define Every Presidency, tells Don how the Chiefs of Staff have impacted the 8 most recent presidents.
