The short answer is no, you can't sue the Social Security Administration over a rude staffer. You should consult with an SS disability attorney about this overpayment issue, the sooner the better. Good luck.
There's no way to answer this question based on the facts you present. There is no law banning the employment of someone with a DUI, just as there is no law requiring it.
