Mark Everson, a Washington fixture under President George W. Bush, is to become vice chairman of Alliant Group, a consultancy that provides tax services to businesses. Everson served as Bush's commissioner of Internal Revenue Service, but may best be remembered for his tenure as president and chief executive of the American Red Cross, which was cut short six months into his term when he was ousted for having an 'inappropriate relationship' with a female subordinate. Speaking of sex scandals, Joel Sawyer, the spokesman who found himself stuck covering for South Carolina Gov. Mark Sanford, R, and whose loyalty helped keep the Luv Guv in office after his romp in Argentina, is resigning to start his own communications consulting firm.
