Why is Trump's team trying to rehire workers they previously fired who oversee the nation's nuclear stockpile?

According to the clip, President Trump's team is attempting to rehire workers they previously fired, specifically those who oversee America's nuclear stockpile. When Stephen Miller was questioned about whether this was a mistake, he explained that these cuts in the Department of Energy were directed by the Senate-confirmed Secretary of Energy. This suggests the administration may be correcting earlier staffing decisions upon recognizing potential gaps in nuclear oversight and security. The situation highlights the complex balance between budget considerations and maintaining proper supervision of critical national security assets.
