Billionaire David Koch Passes Away

Billionaire philanthropist and well-known conservative activist David Koch has died at the age of 79.

Koch’s brother announced his passing Friday morning.

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.
