Wisconsin Governmant Accountability Board:

Four labor unions spent $4.2 million in the first half of 2011 lobbying state lawmakers, according to a report from the Government Accountability Board.
Overall, lobbying organizations reported spending $23.9 million, a 15 percent increase over the first six months of the 2009-2010 legislative session.
The first-half 2011 report analyzes the activities of 707 lobbying principals and 725 registered lobbyists.
“Wisconsin has a strong lobby law which requires that the public has ready access to information on the amount and sources of money used to influence legislation,” said Kevin J. Kennedy, director and general counsel of the Government Accountability Board. “The Board’s Eye on Lobbying online database allows the public to keep track of lobbying activities at the Capitol without leaving home.”
