Burke's disputes with public figures drew nationwide attention in his 4 1/2 years in St. Louis, which seemed to surprise the affable church man who grew up in rural Wisconsin. Some of the targets of his criticism have included John Kerry and Rudy Guiliani, as well as singer Cheryl Crow and basketball coach Rick Majerus.
In 2004, Burke said he would deny Communion to Kerry because of the Massachusetts senator's stance supporting abortion rights. He said the same about Giuliani last year.
