Billionaire David Koch Passes Away
Billionaire philanthropist and well-known conservative activist David Koch has died at the age of 79.
He stepped down last year from helping run the family business, Koch Industries.
With his wealth he built a significant conservative network of donors that work to sway voters to more libertarian ideals.
The organization launched a multi-million dollar campaign last year promoting free trade and warning against tariffs.
Koch also donated millions of dollars to cancer research.
