That one is easy to answer. Because President Obama hasn't fired him and Salazar refuses to resign in shame. (Image)
The real question is what is so wrong with President Obama that he keeps Ken Salazar on as Secretary of the Interior?
Salazar should have given Obama a strong heads up about the major risks of offshore drilling before any policy change was made. He should have done a thorough review of the Department of the Interior with some serious attention to the problem agency key to exploration and drilling permits. The department's Minerals Management Service (MMS) has a long rap sheet as a problem agency. Salazar knew this.
So why is this guy still around?
