Rather than consistently oppose the "Red-baiting" of the late 1940s and early 1950s, Oppenheimer testified against some of his former colleagues and students, both before and during his hearing.
No lugar de opoñerse continuamente ás persecucións políticas de finais dos anos 1940 e comezos dos 1950, Oppenheimer testificou en contra dos seus antigos colegas e estudantes, tanto antes como durante a súa auditoría.
