I couldn’t find any information on an executive order with a date of January 20, 2025, from President Trump that matches the provided text. However, I can provide a summary based on the content of the order:
The executive order directs individuals to perform the functions and duties of certain positions in an acting capacity until the position is filled by appointment.
This order does not specify which positions or individuals are being directed to take on these acting roles, but it implies that there will be temporary substitutions made until permanent appointments can be made.
