The proof is in the fact that he freely and openly confessed that he did what he's accused of . His own chief of staff made the same confession . Backed up with the testimony a several high ranking diplomats whose testimony could not be discredited So just exactly what "absence of proof " are you talking about?
Despite his admission he still had the chance to gather up his documents and along with his subordinates go up to Capital Hill and tell them his side of the story. As president he is completely free to do so......but decided to roll the dice hoping that his minions in the Senate will get him out of the mess he's gotten himself into. With the election less than a year away they'll do it for him this time but if he does this again if I was him I wouldn't count on them doing it a second time.
