So where is the investigation?
It's just ludicrous not to charge an ex-president. It's the fundamental rule of law principle [everyone is subject to law] and the DoJ doesn't vigorously defend it.
And yet US law was used to extort a payment from a member of the British royal family who desperately wanted to avoid embarrassing his mother.
You see how it looks, I hope. Unless the DOJ sorts things out, non-Americans will say that even-handed justice isn't really an American value.
