Timeline of John Doe investigation
MILWAUKEE- The overall scope of John Doe investigation is broad.
It began more than a year and a half ago. This is what we've learned, leading up to Thursday.
Here are some of the key dates.
Spring 2010: The John Doe investigation launched.
August 2010: Officials seized a computer from Tim Russell. Walker's former top aide is one of the men charged.
April 2011: Cullen Werwie, Walker's chief spokesman was offered immunity from prosecution in return for his testimony. He has not been charged.
September 2011: Agents raided Cynthia Archer's home in Madison and seized computers and other records. She's a long time aide to Scott Walker. Archer has not been charged.
December 13th 2011: Milwaukee real estate executive Andrew Jensen was arrested for refusing to cooperate with the John Doe investigation. Jensen has not been charged.
The John Doe investigation continues, so no one knows if any more charges will be filed. Governor Walker maintains he has not been contacted by investigators.
