The remark is indefensible, far more than just simply misspeaking. Rep. Trone should immediately resign from his public office, and never run again. The country does not need racists like him.
Oh, sorry. I just noticed that Rep. Trone is a Democrat. I guess he was just tired. Let’s all move on now.
If this were a Republican who did this to a Democrat staffer, it would be a major national news story - not just about said Republican, but it would be said this is characteristic of *all* Republicans in office.
