What major leadership change is the Department of Homeland Security planning to implement?

The Department of Homeland Security is preparing to fire hundreds of senior leaders this week, according to three sources familiar with the matter who spoke to NBC News. This dramatic leadership shakeup aims to remove individuals who are considered misaligned with the current administration's goals and priorities. The decision represents a significant restructuring effort within one of the government's largest agencies, suggesting an intention to create greater alignment between leadership personnel and the administration's policy objectives. This move will likely have substantial impacts on agency operations and direction in the near future.
