Dean set up the break in to look for his wife’s name on the DNC call girl ring. She was a hooker before he married her.
Yes, IMMIC G. Gordon Liddy was on one of the MSNBC shows in the 90's and noted he wanted to literally kill Dean for the longest time and in a lawsuit deposition it came out that this was about Dean, Sex ( or the Sex is wife was doing for $ before they were an item ) and Nixon covered for him and by extension Nixon took one for the team and Dean IMHO never had the cohones to tell us that the whole Watergate fiasco was about Dean's agenda, not politics. G. Gordon was flummoxed and his attitude changed about Dean. Unfreaking believable that this country was put through this because he married a high class call girl, he had to confirm it, and obviously he didn't want it public knowledge.
A few years after the Watergate event, I attended a talk at my college with John Dean. He babbled on for awhile until the former police detective Frank Serpico, who uncovered police corruption in NYPD, and was in the audience, stood up and accused Dean of lying. I don’t remember his exact words, but it made quite an impression on me.
