David stepped down from his role<br />in the business in June 2018,<br />due to his declining health. Charles Koch,<br />via statement Besides Koch Industries, David is also known for setting <br />up a large political network aimed at garnering <br />votes for Republican politicians. The non-profit he co-founded,<br />Americans for Prosperity, has spent over<br />$1 billion on past elections. Their support of affiliations who deny climate<br />change and oppose gun laws often makes<br />them a target of the Democrats. Socially, David's views were more liberal, <br />as he was a supporter of stem cell research, a <br />woman's right to choose and same-sex marriage. Besides political outreach, Koch also made large<br />donations to medical research and towards the<br />Lincoln Center and the Metropolitan Museum of Art.
