What is the Trump administration planning to do at the Department of Homeland Security?

NBC News has learned that the Trump administration is preparing to implement a centralized plan to fire hundreds of high-level employees across every component of the Department of Homeland Security (DHS). According to three sources familiar with the matter, the administration has compiled a list of people in high-level positions who would be dismissed this week. These new firings would be in addition to hundreds of cuts that already began across DHS on Friday night, suggesting a comprehensive restructuring of the department's leadership. The coordinated nature of these dismissals indicates a systematic approach to reshaping DHS's top ranks.
