OMAHA, Neb. (AP) -- Billionaire Warren Buffett says he's willing to match any contributions to reduce the national debt that Republican members of Congress make.

Buffett told Time magazine about his offer as part of a conversation about why he's optimistic about the nation's future.

Buffett, who is chairman and CEO of Berkshire Hathaway, has been criticized by Republicans for his suggestion that Congress increase taxes on the "mega-rich" like himself. Several Republicans suggested Buffett consider donating money to help the nation balance its books.

Buffett tells Time that he doesn't think many Republicans will be willing to take him up on his offer to match their contributions. Buffett says he'd even triple anything Senate Majority Leader Mitch McConnell gave.

Buffett did not immediately respond Wednesday afternoon to a message from The Associated Press.
