Warren Buffett has challenged Donald Trump over the candidate's refusal to release his tax returns, saying he will meet him "anytime, anyplace" and bring his own income tax return along. The Berkshire Hathaway CEO—whose fortune dwarfs that of Trump—told a Hillary Clinton rally in Omaha, Neb., Monday night that he isn't buying Trump's excuse that he's under audit, because Buffett is also under audit and is free to talk about his taxes, Politico reports. "You're only afraid if you got something to be afraid about. He's not afraid of the IRS. He's afraid because of you," Buffett told the crowd. "I will meet him in Omaha or Mar-a-Lago or he can pick the place," he said. "We're both under audit. And believe me, nobody will stop us from talking about what's on those returns. Send the word to him, if you will."
"You will learn a whole lot more about Donald Trump if he produces his income tax return," Buffett promised. He also brought up Trump's feud with Khizr Khan, looking back to the McCarthy hearings, when Sen. Joseph McCarthy persistently implied that an assistant to Army chief counsel Joe Welch was a Communist. "Joe Welch couldn't take it anymore and he said, and I'll quote him, 'Have you no sense of decency, sir?'" Buffet said. "I ask Donald Trump: Have you no sense of decency, sir?" Nebraska hasn't gone Democratic since 1964, but the Washington Post notes that a quirk in how delegates are awarded means Clinton has a chance at winning an electoral vote from the state's 2nd Congressional District. Buffett promised to bring people to the polls himself and said his goal is for the district to have the highest turnout in the country.
