Josh Lyman

Joshua "Josh" Lyman is a fictional character played by Bradley Whitford on the television drama The West Wing. The role earned Whitford the Primetime Emmy Award for Outstanding Supporting Actor in a Drama Series in 2001. For the majority of the series, he is White House Deputy Chief of Staff and Chief Political Advisor in the Josiah Bartlet administration.
Josh is portrayed as having one of the sharpest minds on the President's staff; he is a witty, somewhat cocky, boyishly charming know-it-all. He is described by Will Bailey as "After Leo... the finest political mind in the party" ("Opposition Research").
