Wisconsin Gov. Scott Walker, fifth from left, salutes the U.S. flag Wednesday, May 7, 2014, during a memorial event in Milwaukee for fallen law enforcement officers. Walker, who scored a major court victory a day earlier when a judge halted an investigation into his 2012 recall campaign, said he is glad the case seems to be approaching an end so he can return to the business of governing.
