From an editorial on the subject here:
Judicial Watch sought those documents because the FHFA claimed in a separate lawsuit against the 17 firms that losses on securities were caused by material misrepresentations the firms made to Fannie and Freddie. Finance industry experts claim Fannie and Freddie officials were more than sufficiently knowledgeable about the mortgage industry to realize the risks involved in such securities. By putting all Fannie and Freddie documents about such transactions beyond the reach of FOIA requesters like Judicial Watch, the Obama administration is making it difficult, if not impossible, for independent evaluators to determine who bears responsibilities for the losses [$150 billion and climbing] now being covered by taxpayers.
