Sen. Ensign Quits GOP Post After Admitting Affair

"Sen. John Ensign of Nevada resigned his Republican leadership post Wednesday, one day after confessing marital infidelity. Aides refused to answer questions about records showing that a woman on his political payroll received a promotion and a pay raise around the time he said the affair began in late 2007. Nor would Ensign or aides respond to reports of an earlier affair, in 2002."
