Menards founder is a $1,000,000 donor to Koch Bros.

Explanation (from 2011):

     Twice a year, the billionaire industrialist brothers Charles and David Koch host secretive retreats for an exclusive list of corporate America's rich and powerful to strategize and raise money for their right-wing political agenda. Mother Jones has obtained exclusive audio recordings that shed some light on the brothers' latest retreat, held at a resort near Vail, Colorado, in late June.
     In a speech that is part of these recordings, Charles Koch thanks donors who gave more than $1 million to the cause. We checked the audio against a list of participants at the Kochs' 2010 seminar in Aspen that was obtained by ThinkProgress.org and did additional research on these individuals. Below are the names Koch read that appeared on the previous guest list.

...John Menard of Eau Claire, Wisconsin, is the founder of Menards, the country's third-largest hardware company. He's worth a reported $5.2 billion and has donated about $80,000 to his state's Republican Party and federal candidates, mostly Republicans, according to FEC records. His company backed a recent anti-union program that was linked to the Kochs' Americans for Prosperity and supported by Gov. Scott Walker.
