(CNN) – Rahm Emanuel, President Obama's chief of staff, is known as a force of nature who efficiently navigates the back halls of Congress to get exactly what he wants.
He is an aggressive political animal who has been known to punctuate his arguments with the F-bomb. Most agree it's not because he's an angry man - it's just part of his foul-mouthed repertoire.
Emanuel's colorful reputation is regularly the subject of Obama's quips. Obama joked at the White House Correspondents Dinner this year that Mother's Day was a difficult holiday for Emanuel because "he's not used to saying the word 'day' after 'mother.' "
But there's so much more to Rahm than his mouth.
