Wisconsin Gov. Walker signs bill restricting secret investigations

Wisconsin Republican Governor Scott Walker on Friday signed a bill into law that prohibits prosecutors from using the state's secret investigation law to probe political crimes - a measure used to convict four of his aides and investigate his campaign.
In Wisconsin, prosecutors can use a so called "John Doe" proceeding law to call witnesses, request search warrants and offer immunity without probable cause that a crime has been committed.
Under the legislation Walker signed, prosecutors can no longer use the law to investigate cases of bribery or political misconduct. Instead, the law is limited to the investigation of certain crimes, such as ones involving violent felonies.
