More information has come to light about the close ties between Wisconsin Governor Scott Walker and David and Charles Koch, the billionaire brothers who helped bankroll the Tea Party movement. According to Wisconsin campaign finance filings, Koch Industries funneled $43,000 to Walker’s gubernatorial campaign, making it one of Walker’s biggest contributors. In addition, Koch Industries gave more than $1 million to the Republican Governors Association, which played a key role in the Wisconsin race. Since taking office, Walker has been in close contact with Americans for Prosperity, a Koch-funded organization. The head of the organization, Tim Phillips, told the New York Times that his group had worked behind the scenes to try to encourage a union showdown in Wisconsin.
