The American billionaire investor, in the new issue of Time magazine, says he would donate $1 to paying down the national debt for every dollar donated by a Republican in Congress. The only exception is Senate Republican leader Mitch McConnell – for whom Buffett said he would go $3-to-$1.
The idea stems from a New York Times opinion piece Buffett wrote last August in which he said the rich ought to pay more taxes. It sparked an instant controversy, with some Washington conservatives calling on the 81-year-old "Oracle of Omaha" to voluntarily pay extra.
McConnell said at the time that if Buffett felt "guilty" about paying too low a tax rate, he should "send in a check." This was quickly followed by introduction of a bill to give taxpayers an option on tax forms to make voluntary donations.
