President issued Executive Order 14136, outlining a new order of succession for the Department of Justice. According to the order, if the Attorney General and their top deputies can't perform their duties, the U.S. Attorneys from New York's Southern District, Arizona, Illinois's Northern District, and Hawaii will step in, in that order. The order also specifies that acting officials can't serve as Attorney General unless eligible under the law, and the President has the discretion to change this order. This order replaces a similar executive order from 2017.
Simple Explanation
The President made a new plan for who takes charge in the Department of Justice if the main leaders can't do their job. It starts with some special lawyers from New York, Arizona, Illinois, and Hawaii, but only if they are allowed by law.
