This Friday, Need to Know focuses on a potential problem looming on the horizon — that of a national commercial real estate foreclosure crisis — and another problem that has already become a global epidemic — malnutrition. Read on for more details!

Alison Stewart sits down with Elizabeth Warren, attorney, Harvard Law professor and chair of the Congressional Oversight Panel, in a “Blueprint America” special report about the potential of a national commercial real estate foreclosure crisis, which has already hit Atlanta.
