Billionaire conservative activist, David Koch, has died.
He was 79 years old and a philanthropist.
David and his brother, Charles, co-owned Koch Industries, a Nebraska-based energy and chemical company, since 1983.
He stepped down from running the Koch organisation in 2018 due to declining health.
The Koch brothers helped to build a massive conservative network of donors for organizations that work to mobilize voters and sway elected officials in support of libertarian-leaning economic policies.
