A body man assists an executive branch official or political candidate by shadowing him at virtually all times.
The term was first used in a 1988 Boston Globe article, which said that body men “fulfill a kind of mothering role,” securing their bosses accommodations and ensuring he always has his favorite breakfast. Past body men have become very close with their employers: George W. Bush’s body man, Blake Gottesman, dated Bush’s daughter Jenna, and Richard Nixon’s body man followed his boss into retirement.
William Safire: “The informal job title is not be confused with the man with the briefcase, the ever-present carrier of the codes needed by the president to respond to a hostile missile launch. It is more specific and intimate than gofer, a term applied to any aide ready to ”go fer” coffee or do other menial tasks.”
