New details have emerged on the right-wing groups spending tens of millions of dollars to influence the upcoming midterm elections. The website ThinkProgress reports the billionaire brothers David and Charles Koch held a secretive meeting with influential right-wing figures in June to plot their election strategy and lobbying activities for this year. The 210 attendees included executives from the oil industry, coal companies, health insurers, banks, right-wing pundits including Glenn Beck, and officials from the US Chamber of Commerce. The gathering was the latest in a series of bi-annual gatherings organized by the Koch brothers, who have quietly helped bankroll the Tea Party movement and dozens of other right-wing causes.
