I remember the Saturday Night Massacre, McCain told the mostly European and American guests, referring to the 1973 incident when President Nixon fired the special prosecutor looking into the Watergate break-in, Archibald Cox.
Hadn’t he just gotten out of the Hanoi Hilton in 1973?
Good question, not 100% on the answer.
Your point on release from Hanoi in 73 may be accurate.
I wasn’t in that part of the discussion but I did hear Archibald Cox at a lecture in college. Not a big turnout but I was there to hear about the history.
Cox fwiw seemed to be a fine fellow and light years from the politicized operators under Clinton and Obama holding DoJ responsibility.
