Warner's right.  The investigation needs to be allowed to go where it goes.  This will either clear Trump or implicate him but firing Mueller or pardoning those indicted would be seen by the world as motivated by guilt and as obstruction of justice.  For the future of the GOP, the American justice system and the Trump administration, this controversy must be brought to a legitimate conclusion. Obfuscation, accusations and disproven denials won't do, we need to establish what happened, whether, or which, people were involved and stop Russian meddling in our future elections
