Conservative big Koch is retiring

BILLIONAIRE conservative icon David Koch is stepping down from the Koch brothers’ network of business and political activities.

The 78-year-old New York City resident is suffering from deteriorating health, according to a letter that older brother Charles Koch sent to company officials Tuesday morning.

Charles Koch wrote that he is “deeply saddened” by his brother’s retirement. “David has always been a fighter and is dealing with this challenge in the same way,” he wrote.

David Koch is leaving his roles as executive roles at Koch Industries and subsidiary Koch Chemical Technology group.

He is also stepping down as board chairman of the Americans for Prosperity Foundation, the charity related to the brothers’ primary political organization.

Democrats have demonized the Koch brothers for their outsize influence in conservative politics over the last decade. Yet the brothers have clashed with the Trump administration at times.
