The grand jury going after Nixon found that he had no knowledge of the Watergate break in. He was guilty of with holding evidence from the grand-jury.( not a impeachable offense unless you are a Republican).
In this case obama committed fraud and deception to cover up the fact that he is not a Natural Born citizen( if he is even a citizen). His supporters have harassed and intimidated anyone that questions his right to be “President”. These are criminal acts committed by obama and he has not yet even been charged with a crime. We have became a third world nation!!
I think you meant to say, "PRIOR knowledge of the Watergate break in."
Nixon certainly knew why the hush money was needed and I recall that Nixon was named as an "unindicted co-conspirator". The grand jury was probably reluctant to indict a sitting President. Nixon surrounded himself with amoral henchmen and doesn't deserve being treated as if he didn't know that.
