In normal circumstances, the President's former personal lawyer striking a plea deal with the President's friend in prison looks bad, but if the goal now is to get her to supposedly exonerate the President from his current scandal, then that is wrong, no matter what the President's friend says now.
Normalizing this type of corruption is how countries end up as completely failed states run by organized crime. We should not let the President avoid personal scandals by permitting him to send his former personal lawyer to get any testimony from the President's incarcerated friends. That is crazy.
