When Wisconsin Governor Scott Walker met with a billionaire campaign donor a month before he launched his attack on the collective-bargaining rights of public-sector workers and public-school teachers, he engaged in a detailed discussion about undermining unions as part of a broader strategy of strengthening the position of his Republican party.

After he initiated those attacks, Governor Walker testified under oath to a Congressional committee. He was asked during the April 2011 hearing to specifically address the question of whether he set out to weaken unions—which traditionally back Democrats and which are expected to play a major role in President Obama’s 2012 re-election campaign—for political purposes. Walker replied: “It’s not about that for me.”
