Warren Buffett to Advise Democrat Kerry

Warren Buffett, the billionaire investor who has publicly criticized President Bush's tax cuts as favoring the wealthy, said Sunday he has agreed to serve as an economic adviser to John Kerry.

Buffett, a Democrat, said he and Kerry have spoken once — when Kerry called to ask if Buffett would be willing to serve with a group of advisers that includes Roger Altman, deputy treasury secretary under President Clinton, and former Clinton economic adviser Gene Sperling.
