Who is Fletcher Coal from The Pelican Brief and what is their importance?

Fletcher Coal is the White House Chief of Staff, Coal at 37 runs the operation for a weak, disinterested President. He is the boy wonder who rescues a failing campaign as a guileful manipulator and nasty henchman. Coal hates the directors of the CIA and the FBI—and it is fully mutual. He stands during meetings like a sentry at the window, and paces annoyingly like der Führer before the President's desk. The President hates Coal's perfection. He is said to work 20 hours a day, seven days a week, 5 AM until 11 PM, and fires subordinates who fail to put in 80 hours a week against his 120. He drinks only water, eats from vending machines, has perfect recall, devours information, is never relaxed, and sleeps 3-5 hours a night. His appearance is always perfect.
