You must be new to American politics. Once a United States President leaves office the rest of his administration leaves with him and the new President immediately stops any investigation of the old administration. If things were not done this way it would be way to tempting to start killing your rivals for fear retaliation.
Lotta crap, (congressmen), riding on Obamas birth certificate. And it is NEVER going to go away as it is SO PUBLIC. While wicked men prey, believing that justice will never have its way, history teaches us that rarely is true.
There will be Justice in the end, as there is a God that will insure it is so.
That may have been so in the past but how many of Hussein's thugs will remain in their department positions? Maybe his immediate staff but there are others who will carry on his ideas. How many Supremes will retire? How many Congress critters will resign? No, they're there to bring about change and they're not leaving any time soon.
