New Details Emerge of Secret Investigation of Wisconsin Governor's Campaign

As Gov. Scott Walker this week promotes the release of his book "Unintimidated," new details are emerging about an ongoing criminal investigation that reportedly focuses on his campaign and other conservative groups.

The Wall Street Journal reported Friday that Walker's campaign and more than two dozen conservative groups have been subpoenaed by a special prosecutor seeking records and fundraising information related to a series of recall attempts in 2011 and 2012 that targeted Walker and Republican state senators.

The news came just days before Walker made the rounds on national television shows Sunday promoting his book, which focuses heavily on the recall efforts and the fight over public union collective bargaining that precipitated them.

The book, which comes out Tuesday, is fueling speculation that Walker might run for president in 2016.

But Wisconsin Democratic Party Chairman Mike Tate, in a conference call Monday, said the investigation shows why Walker needs to be replaced as governor next year. His only Democratic challenger to date is a former Wisconsin commerce secretary, millionaire Mary Burke, whose father founded Trek Bicycle Corp.
