Billionaire investor Warren Buffett has endorsed Hillary Clinton and challenged Trump to release his tax returns. Buffett also ridiculed Trump’s business acumen, saying Trump had let down investors in his businesses.

Warren Buffett: “If a monkey had thrown a dart at the stock page, the monkey, on average, would have made 150 percent. But the people that believed in him, that listened to his siren song, came away losing well over 90 cents on the dollar. They got back less than a dime.”
