A good read...Not bad. It's a 2002 transcript. The money quote from it is this...
"First of all, government sponsored corporations that help create our mortgage system -- I introduced two of the leaders here today -- they call those people Fannie May and Freddie Mac, as well as the federal home loan banks, will increase their commitment to minority markets by more than $440 billion. (Applause.) I want to thank Leland and Franklin for that commitment. It's a commitment that conforms to their charters, as well, and also conforms to their hearts. This means they will purchase more loans made by banks after Americans, Hispanics and other minorities, which will encourage homeownership. Freddie Mac will launch 25 initiatives to eliminate homeownership barriers. Under one of these, consumers with poor credit will be able to get a mortgage with an interest rate that automatically goes down after a period of consistent payments."
Anyway starting around 2003 the administration began to warn about mortgage GSE's.
