This executive order represents a significant shift in personnel management within the federal government, concentrating power in the hands of agency heads and potentially undermining established legal frameworks and merit-based principles. The order's reliance on executive authority to supersede existing regulations, coupled with the broad discretion granted to agency heads in determining employee continuation, raises serious concerns about democratic erosion and the rule of law. The requirement for a 'public interest' certification introduces a subjective element that could be vulnerable to political influence.
