Former Nixon White House counsel John Dean characterized the first day of public impeachment testimony against President Donald Trump as both thorough and damning, saying House Democrats “already have more than they had against Richard Nixon to impeach him. Just on all accounts.

Dean, who has become a vocal, voluble critic of Trump, made his comments to a massive, nine-person panel during CNN’s AC360. Dean famously turned against his former boss and became the star witness in the House impeachment investigation of Nixon’s misconduct in the Watergate scandal.

“John, I mean, given what you saw today, did this move the needle for any Republican senators who are watching?” CNN host Anderson Cooper asked Dean.

“There’s a conspiracy, we know from what’s come out of the executive sessions, generally, where this is going,” Dean said. “What struck me today in listening to these two witnesses is they already have more than they had against Richard Nixon to impeach him. Just on all accounts.”

“Why do you say that?” asked fellow panelist, CNN legal analyst Jeffrey Toobin.

“Because the evidence is there,” Dean responded. “It was my testimony, a few people that were lower in the pecking order than me, and it happened before the tapes.”

Unlike the already released call summary where Trump is seen soliciting an investigation into his potential political rival, the blockbuster revelation that a White House taping system existed only came out weeks after Dean’s testimony in June 1973. The subsequent legal fight by the Nixon White House to prevent releasing the tapes to Congress became another impeachable offense and the infamous 18-and-a-half-minute gap on a tape where Nixon discussed the Watergate break-in became a key piece of evidence proving the Nixon cover-up.
