According to the Government Accountability Board's website, the firm has seven lobbyists who "represent various Koch Industries Inc. companies on public affairs matters, including Flint Hills Resources, LP, an energy purchaser and refiner & transporter of petroleum and Georgia-Pacific, LLC a manufacturer of paper, wood products and building materials." The group's lobbying interests are listed as "the environment, energy, taxation, business, policy and other areas affecting Koch Industries, Inc. companies."

The group has had a lobbying presence in the state before, with four contracted lobbyists from Hamilton Consulting billing just over $97,000 for services during the 2009-11 legislative session, according to the GAB. Three of those lobbyists — Amy Boyer, Andrew Engel and Robert Fassbender — are now joined also by Ray Carey, Jason Childress, Kathleen Walby and Jeffrey Schoepke.

The lobbyists for Koch Companies Public Sector registered with the state on January 5, two days after Walker's inauguration.

The expanded lobbying effort by the Koch brothers in Wisconsin raises red flags in particular because of a little discussed provision in Walker's repair bill that would allow Koch Industries and other private companies to purchase state-owned power plants in no-bid contracts.
