Milwaukee County District Attorney John Chisholm is investigating former aides to Wisconsin Gov. Scott Walker's former aides. But Chisholm's chief investigator has his yard and home festooned with "Recall Walker" and blue-fist signage. "I do not regulate or control the constitutional freedoms of my employees' families in their private lives," Chisholm wrote in defense of chief investigator David Budde. "They have the right, under state law, and in this case, county civil service rules, to express their political views as does any other citizen." But WisconsinReporter.com's Matt Kittle shows how Budde's activities cast doubt on the objectivity of Chisholm, a Democrat, and his office in a county that is a stronghold for union Democrats.
