Adam Feinberg discusses the DOJ’s investigations into whether mortgage lenders defrauded the government by improperly accessing federal guarantees on mortgage debt, which could lead to prosecutions under the False Claims Act (FCA). "We're about to see a slew of this," says Feinberg. "Twenty years ago, health care fraud was not that big a deal. Now it is the single biggest use of the False Claims Act. Mortgage fraud is going to be the next big wave."
