They both obtained licenses to practice law, but were terminated without any explanation as to why or by whom. Would be very interesting given the fact that both of them were involved in some shady circumstances where hundreds of thousands of dollars changed hands with very little supporting evidence...
They voluntarily retired their licenses. This is not unusual at all. Lawyers who change careers do it all the time.
Michelle was not hired as legal counsel for the hospital. She was hired to move poor sick people who couldn’t pay their bills out of the hospital and foist them on some other hospital. Then when her husband was elected to the Senate her job was to lobby him to give tax dollars to the hospital. She did both jobs well but neither needed a law license to do them.
Barry never practiced law. Probably because he was incompetent.
