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:
The Republican party candidate for president has more than a dozen of billionaire backers supporting his campaign. Though Fortune and others have questioned Trump’s own personal wealth claims, other members of the three comma club have thrown their weight behind him.
Who among them has raised the Trump banner? People on the list range from Peter Thiel, the Silicon Valley investor of PayPal (PYPL) and Facebook (FB) fame who keynoted this year’s Republican National Convention, to Sheldon Adelson, the Las Vegas Sands Casino (LVS) impresario, to Woody Johnson, owner of the New York Jets football team and heir to the Johnson & Johnson (JNJ) fortune, to Carl Icahn, the rough-and-tumble activist investor and chairman of the eponymous Icahn Enterprises (IEP). (Sorry, Martin Shkreli, the ex-CEO of Turing Pharmaceuticals, did not make the cut.)
Here’s the lineup of ultra-rich bigwigs championing the reality television star-turned-politician in the 2016 election.
