Elizabeth Warren, the creator and presumptive head of President Barack Obama?s controversial new consumer finance protection agency, has been invited to headline UW-Madison?s annual spring conference on housing and the economy. If she can make it — she?s been invited, and by now must be expected, but hasn?t yet formally agreed — Warren will discuss how her agency, the Consumer Financial Protection Bureau, will affect the housing industry, according to the agenda for the June 9 event, dubbed “New Partnerships: Government and Real Estate.”
