Who will succeed Warren Buffett?
Warren Buffett has called for Congress to make him and his "mega-rich friends" pay more income tax.
In a piece in the New York Times newspaper, the billionaire investor and philanthropist said the rich should do more to help plug the deficit.
He called for a tax rise for those earning more than $1m (£600,000), and a higher rate for those on over $10m.
In a rebuttal of arguments made by Republicans, he said tax rises would not hurt investment or jobs in the US.
He told Congress to "stop coddling the super-rich".
