WASHINGTON—Mark Calabria has a message for Congress: Help the Trump administration overhaul mortgage-finance companies Fannie Mae and Freddie Mac, or he will do what he can on his own.
The two companies, critical to half the nation’s mortgages, have been under government control since the 2008 financial crisis. For over a decade, policy makers have tried and failed to return them to the private sector and scale back the government’s role in housing.
What could go wrong?
