From today's National Post:

U.S. regulators Friday subpoenaed JPMorgan Chase & Co., Citigroup Inc., Bank of America Corp., Goldman Sachs Group Inc. and Wells Fargo & Co., seeking information on the banks’ role in bundling mortgages for sale to investors, a person familiar with the matter said. The Securities and Exchange Commission subpoenas asked the banks for details on how mortgages were selected and bundled into securities, said the person, who declined to be identified because the probe isn’t public. The SEC, which is investigating business practices that might have contributed to the collapse of the U.S. subprime mortgage market, has sued companies and executives responsible for selling loan bundles that soured when the housing bubble burst. Goldman Sachs reached a US$550-million settlement over SEC claims that it misled investors.
