When the Fed released its "trove" of materials confirming that the Fed indeed knew that the Barclays was manipulating its Libor submissions (amusingly explained by Ben Bernanke before Senate today that "the employee had no idea what Libor is in that case"), few were surprised, but more were confused why the congressional inquiry focused solely on the Fed's interactions with British Barclays, instead of focusing on the three domestic banks that were part of the BBA's USD Libor fixing committee.Sure enough, the 3 US banks on the USD Libor fixing committee were just dragged into the fray:

They are BofA, JPMorgan Chase, and Citigroup. What, no Goldman Sachs? Oh, I expect they'll be part of the investigation soon enough
