Only one of the billionaire Koch brothers supported Donald Trump’s 2016 campaign: William Ingraham Koch. Bill Koch even raised money for Trump, his nearby neighbor in Palm Beach, Fla.
That same year, IRS criminal agents began an investigation after receiving nearly 1,000 pages of documents detailing what were described as multiple tax frauds at Bill Koch’s companies. The documents, which we call the Koch Papers, came from a deeply knowledgeable source: Charles Middleton, who had been one of the companies’ top tax executives.
