But don't get your hopes up. On Obamas way out the door he will issue a general pardon for her that will make her immune to prosecution. Nixon was never impeached or convicted of anything. The impeachment process was started in the House but never came to the floor for a vote. Nixon resigned. Gerald Ford issued a general pardon to him that insulated him from ever being charged with anything.
The Constitutionality of giving pardons for lack of indictments or convictions is highly dubious. Nixon’s pardon was not challenged. Trump may challenge some open ended pardon that Obama gives to these criminals. At the very least, Trump will do an official government report to tell the truth for all the world to see of the Clinton’s criminality.
