The Archdiocese of Milwaukee is pushing back against a recently announced attorney general investigation into sexual abuse by Catholic clergy, calling it a display of "anti-Catholic bigotry" and a violation of the First Amendment. In a letter from the archdiocese's attorney, Frank LoCoco of the Milwaukee firm Husch Blackwell, contends Attorney General Josh Kaul doesn't have the authority to investigate the Catholic dioceses of the state and that doing so would go against the U.S. Constitution and state laws.
