Mr Vance's thoughts are more about the current administration that he is a part of, than the Nixon administration. His desire is to not be held to the level of accountability that president Nixon was. Mr Vance's claim that they do Watergate level things twice daily (1) may be true, but it is IMHO not positive and should not be a boast. Accountability is good.
