FILE - Wisconsin Gov. Scott Walker speaks to the Illinois Chamber of Commerce in this April 17, 2012 file photo taken in Springfield, Ill. Lost in the hoopla over the effort to recall Wisconsin Gov.

Democrats have started playing up questions about why Walker created a criminal defense fund for himself and whether the governor might face charges next. (AP Photo/Seth Perlman, File) less
