Brennan: "Grounds for Disqualification"

Wisconsin Gubernatorial Candidate Joel Brennan talks about how Wisconsin Lieutenant Governor Sara Rodriguez fired her longtime campaign manager, following the discovery of widespread financial irregularities and "egregious" reporting errors. Why does he view her actions as grounds for disqualification rather than a sign of swift accountability? What is his message to nervous Democratic donors who are now worried that institutional campaign funds are being mismanaged in this race? What specific internal financial checks and balances do campaigns employ to prevent the kind of "egregious reporting errors"?
