David McKean grew up in South Hamilton, Massachusetts. He was educated at Harvard College and holds graduate degrees from Duke Law School and the Fletcher School of Law and Diplomacy. More than a decade ago McKean began his career in government working for Senator John Kerry of Massachusetts. He is a former chief of staff to former Congressman Joseph P. Kennedy II and is currently the chief of staff to a member of the United States Senate. As a measure of how some things have changed in Washington since the days of Tommy Corcoran, the Senate Ethics Committee has advised McKean to withhold the name of the senator he currently works for so as not to create the appearance of using his position in the U.S. government for commercial purposes. McKean is coauthor of the biographyFriends in High Places: The Rise and Fall of Clark Clifford.
