I think this was his "come clean" moment with an eye toward a career in politics after laying low for a while. (Maybe he got some sound advice from Clinton)
There was talk a few years ago of him running for Texas governor. That got squashed fast. With the loss of his titles and lies, he has even less chance in an elected position. Of course, the choom in chief could find they’re kindred souls and appoint him as Drug Czar.
