What is the purpose behind the Trump administration's mass firings at the Department of Homeland Security?

The Trump administration is executing a centralized plan to fire hundreds of high-level employees across all DHS components, including ICE and CBP. The primary goal is to replace career officials with Trump loyalists who will implement the administration's policy priorities, particularly mass deportations. The firings target Senior Executive Service (SES) personnel who are deemed insufficiently loyal to Trump or haven't actively demonstrated support for his agenda. This loyalty assessment looks at whether officials appear fully on board with administration policies or might have leaked information to media. The strategy prioritizes short-term disruption for long-term control by installing people who will make decisions aligned with Trump's immigration enforcement vision.
