WASHINGTON — A member of Sen. Rand Paul's staff who helped him write one of his books is aformer pro-secessionist radio commentator who wore a Confederate flag mask during public appearances, according to a news report Tuesday.

Jack Hunter, who is Paul's director of new media and credited writer with the senator on the 2011 bookThe Tea Party Goes to Washington, has called himself the "Southern Avenger" since 1999 and has expressed support for the assassination of President Abraham Lincoln, according to the Washington Free Beacon, a conservative online news site.
