On Monday, Warren Buffett attacked Donald Trump’s business acumen, saying a monkey could have done far better running a public company than the Republican nominee did. Buffett also challenged Trump to release his tax returns.
Buffett is one of a number of billionaires who have lined up in support of the Democratic party contender, Hillary Clinton. Her endorsers also include mogul and former NYC mayor Michael Bloomberg and Apple CEO Tim Cook.

Still others are dissatisfied with both options for the executive office. At Fortune’s Brainstorm Tech conference in Aspen, Colo., this summer, the mega-wealthy industrialist Charles Koch, a longtime conservative backer, likened voting for either candidate to choosing between “cancer or a heart attack.” (We left him off the list.)
But when it comes to big bucks donors, Donald Trump is not going it alone, either.
For more billionaires’ thoughts on Trump, watch:

(Sorry, Martin Shkreli, the ex-CEO of Turing Pharmaceuticals, did not make the cut.)
