Koch brothers quietly open lobbying office in downtown Madison

The billionaire brothers whose political action committee gave Gov. Scott Walker $43,000 and helped fund a multi-million dollar attack ad campaign against his opponent during the 2010 gubernatorial election have quietly opened a lobbying office in Madison just off the Capitol Square. Charles and David Koch, who co-own Koch Industries Inc. and whose combined worth is estimated at $43 billion, have been recently tied with Walker's push to eliminate collective bargaining rights for public workers. The two have long backed conservative causes and groups including Americans for Prosperity, which organized the Tea Party rally Saturday in support of Walker's plan to strip public workers of collective bargaining rights and recently launched the Stand with Scott Walker website. Tim Phillips, president of Americans for Prosperity, acknowledged in a New York Times story Tuesday that he had encouraged Walker even before the election to mount a showdown with labor groups.
