I don't think ANYTHING will happen under this administration or Congress. The only thing that can address it will be elections. The press are just too friendly to the current administration to ever rake them over the coals like they did Nixon. Congress has no legal maneuver against it. The Admin will not discpline themselves. And the press will not rail for impeachment.
"The ultimate authority ... resides in the people alone. ... The advantage of being armed, which the Americans possess over the people of almost every other nation ... forms a barrier against the enterprises of ambition."
