Yes, he did start with Nixon. He even has a tattoo of Nixon on his back. Information I’ve seen leads me to believe that, while Nixon wasn’t completely innocent regarding Watergate, he was set up by the CIA. They were upset with him trying to bring an end to the Vietnam war. In other words, they planned the break in, sabotaged it so it would fail, and counted on Nixon covering things up after the fact.
After everything we have been witnessing for the past three years I have no doubt that could be true. More than three if you count the campaign.
