Elizabeth Warren, the leader of President Barack Obama?s controversial new mortgage industry watchdog, the Consumer Financial Protection Bureau, will not speak at a UW-Madison conference on real estate and the economy this week. But she is sending an official from her agency, Patricia McCoy, to give a short presentation about the CFPB?s new mortgage disclosure program. Other speakers include Gov. Scott Walker, U.S. Rep. Paul Ryan and Michael Knetter, former dean of UW-Madison?s School of Business and now president of the UW Foundation.
