The lack of a plan to aid homeowners facing foreclosure was one of several major issues members of Congress took with the Whitehouse’s $700 billion economic bailout plan yesterday, as the Senate Banking Committee questioned Treasury Secretary Henry M. Paulson Jr. and Federal Reserve Chairman Ben S. Bernanke on the proposal for five hours. Democrats in the House of Representatives have been pushing for a measure that would allow bankruptcy judges to modify the terms of mortgages on primary homes for those who could not afford their loan payments. It remains unclear whether Congress will pass a version of the proposed plan this week.
