That’s just being silly. The word “reign” gets used pretty loosely. At my workplace, the CEO often refers to the “reign” of his predecessors. Hell, my wife has reign over the house which is why I need to go to Buffalo Wild Wings when I want to watch a football game and have a few beers in some peace and quiet.
Hope someone does ask Trump about it. He might (probably would) clarify that it isn’t some big deal, by way of example.
