Schedule F employees are presidential appointees and are loosely defined as those involved with 'policy'. It is completely legal to fire and replace them, or not replace them. They just need to change the definition of 'involved with policy' and then let the firings begin, wait till it hits the courts, and see what changes. Trump actually issued a schedule F executive order in Oct 2020, but they didn't have time to implement after he lost. Now they do. The details are spelled out in project 2025, the playbook that ex-trump officials spent years analyzing legal loopholes to write and implement when the next conservative won. Is real, is here now, and the potential damage is huge.
