Well, Charlie Rangel is the one who replaced Adam Clayton Powell, as it happens (at least I think so).

His 'sins' are small potatoes, but not totally made-up. The committee seems to have offered him censure, which is below removal from office on the Congressional scale of punishments. As you say, not up there with that Ensign clown. It's interesting that John Boehner seems to 'handle' Republican miscreants 'privately,' while Democrats go to the ethics committee, where the five Republican members insist on lots of publicity, and at least one Democrat goes along with it.
