Johnson wasn't the CEO of CountryWide. He was, however, the CEO of Fannie Mae which was CountryWide's biggest customer. As the CEO of Fannie Mae he got millions in loans from CountryWide, a FoA (Friend of Angelo Mozilo the CEO of CountryWide).
He's also on the board of Goldman Sachs, The Brookings Institution, and is a member of Americans for Bilderberg group. A business partner of George Soros, member of the Trilateralists, and CFR.
While at Fannie Mae, they reported billions in profits that were "creative" and had to be restated (I believe these are still under investigation for criminal actions).
