In political news, the billionaire right-wing Koch Brothers are back in the news. A new investigation from the Associated Press has exposed deep ties between Republican presidential hopeful Herman Cain and David and Charles Koch, the brothers who helped bankroll the Tea Party movement. Cain’s campaign manager, his former spokesperson and at least six other current and former paid employees and consultants have worked for the Koch-funded Americans for Prosperity. Cain also credits a businessman who served on an AFP advisory board with helping devise his “9-9-9” plan to rewrite the nation’s tax code.
