The Biden administration is reversing a 1954 decision that revoked J. Robert Oppenheimer's security clearance.
Oppenheimer, known as the father of the atomic bomb, was a leading researcher in theoretical physics and played a key role in the creation of the atomic bomb during WWII.
Oppenheimer later came under suspicion due to his association with progressive causes and opposition to the development of the hydrogen bomb.
The Atomic Energy Commission launched an investigation and stripped Oppenheimer of his security clearance in the 1950s.
The Department of Energy is now calling the investigation a "flawed process" and reversing the decision.
The decision comes after decades of lobbying from the scientific community to clear Oppenheimer's reputation.
The Department of Energy is also reversing the decision to correct the historical record and honor Oppenheimer's contributions.
Oppenheimer died in 1967, and a film about him is set to be released in July.
