Obama Enlists Millionaires in Buffett Rule Campaign

President Barack Obama is intensifying his campaign for higher taxes on top U.S. earners by casting the issue against Republican opposition as one of fairness and support for the middle class.

Obama enlisted what the administration described as a group of four millionaires and their assistants, all of whom support the so-called Buffett rule to set a minimum tax on people who earn at least $1 million annually.
