Teller testified against Oppenheimer at Oppenheimer's AEC security clearance hearing.When I was real young Oppenheimer was 'the hero' for ending WWII with 'his' A Bomb.
Then maybe 40 years ago on 60 Minutes(?) Teller was interviewed about the H Bomb and his 'vocal opponent' Oppenheimer. After that Heller became my good guy and I considered Oppenheimer almost a traitor for his opposition to the USA staying ahead of the Commie B-turds in the USSR with nukes.
(This would have been back in Mike Wallace's early 'good guy days')
