WASHINGTON -- The Biden administration has reversed a decades-old decision to revoke the security clearance of Robert Oppenheimer, the physicist called the father of the atomic bomb for his leading role in World War II’s Manhattan Project.

The decision comes as the story of Oppenheimer is headed to the big screen. Christopher Nolan's “Oppenheimer” film is expected to be released in theaters in July. 

It's based on Kai Bird and Martin J. Sherwin’s Pulitzer Prize-winning biography “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer,” and stars Cillian Murphy in the title role.
