Sanders Investigation to Continue
The complaint was brought against Sanders by the perpetually outraged RussandDee, of Birmingham talk radio notoriety. You can read the article and decide for yourself whether Sanders abused his position.
Sanders is about as safe as possible in his district and it would take quite a bombshell to put him in any direct political danger. But if the Ethics Commission does come down hard on him, Senate Republicans might be able to use the issue in the coming elections.
The Ethics Commission will continue to investigate and will meet in February to publicly address the issue again.
