Billionaire investor Warren Buffett is no fan of Donald Trump.
"I ask Donald Trump: Have you no sense of decency, sir?" Buffett said.
The Berkshire Hathaway CEO appeared at a rally with Hillary Clinton in his hometown of Omaha, Nebraska. He says he's reserving a 32-seat trolley to take voters to the polls on Election Day to help defeat Trump.
He also offered to meet Trump so they can both release their tax returns.
"Nobody is going to arrest us," Buffett said. "There are no rules against showing your tax returns. And just let people ask us questions about the items that are on there. You're only afraid if you've got something to be afraid about."
Trump has said he'll release his returns once an IRS audit is done.
