David Koch, the billionaire and major conservative donor, has died at 79. 

“It is with a heavy heart that I announce the passing of my brother David,” Charles Koch, his older brother and half co-owner of Koch Industries, confirmed in a statement Friday. “Anyone who worked with David surely experienced his giant personality and passion for life.”

Koch’s health had been deteriorating for some time. In a June 2018 memo sent to Koch Industries employees, it was announced that Koch would be retiring due to declining health. (He was diagnosed with prostate cancer in the 1990s.)

The Koch brothers spent decades using their fortune building a vast network of conservative political causes. As we explained when Koch Industries announced his retirement last year:

The brothers have given hundreds of millions of dollars—and convinced other wealthy conservatives to contribute even more—to support think tanks, politically active dark money groups, and academic research, all carefully designed to foster ideological support for conservative and libertarian ideas. 

[…]

David Koch is the most directly political of the pair, having actually run for office himself: In 1980, he ran for vice president on the Libertarian Party ticket, self-financing most of the campaign.

This is a breaking news post. We’ll update as more information is confirmed.

More Mother Jones reporting on Dark Money

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
