Perhaps, fellow freaking pie-hole Dmitry, there are CO’s at Fannie and Freddie too, or the equivalent. The folks who sign contracts for services and goods? Do you think?
Freddie and Fannie employees are not GS level employees. In order to understand this you have to understand the Federal Hire system. Once again the only GS level, or YC, level employees that can go to jail or be held financially obligated for their decisions are Contracting Officers.
