I want to know the answer to the following question:
Peter J. Wallison believes that the one of the roots of the financial crisis can be traced to affordable housing policies by which agency in the 1990s?
All the background I'm provided with is that "Later, based upon information in the SEC's December 2011 securities fraud case against 6 ex-executives of Fannie and Freddie, Peter Wallison and Edward Pinto estimated that, in 2008, Fannie and Freddie held 13 million substandard loans totaling over $2 trillion.". Is that enough to answer the question?
Answer: no
