Both the government and Goldman Sachs & Co. released a flurry of documents over the weekend as both sides prepared for a showdown in a Senate hearing today. The hearing is looking into whether the giant Wall Street bank profited during the financial meltdown by selling subprime mortgage investments that were secretly designed to fail.

Seven Goldman executives are expected to testify today before the Senate Permanent Subcommittee on Investigations. The subcommittee is part of the Homeland Security and Governmental Affairs Committee and has jurisdiction to conduct investigations into a broad range of issues.
