One Deep Throat question that can never be answered

How did Felt feel as he watched RN appear as a defense witness at his trial? Was there any twinge of guilt or second thoughts about helping Woodward?

Nixon Spoke on Behalf of Felt in Court

In a strange footnote to history, Richard M. Nixon unwittingly testified on behalf of Deep Throat in a federal court trial in October 1980 -- six years after Nixon was forced to resign as president because of his involvement in the Watergate scandal.

Maybe that was part of the reason he was reluctant to claim credit in later years.
