Why is President Trump's team trying to rehire workers who oversee the nation's nuclear stockpile, and is this a standard procedure?

Trump's team is attempting to rehire Department of Energy workers who oversee the nation's nuclear stockpile after they were previously fired. Stephen Miller claims this is standard downsizing procedure directed by the Secretary of Energy, where cuts are made and then reassessed to determine who should be rehired. However, Ron Insana strongly disagrees, emphasizing that these aren't routine staffing adjustments but involve highly sensitive nuclear security positions requiring top-level classification. Unlike corporate downsizing, these positions are critical to national security and cannot be treated as standard redundant workforce reductions.
