A "try to fire" includes any of the following:
- The President signs an executive order, memorandum, or other official document stating termination;
- Directs any Cabinet member or senior official to terminate the person;
- Publicly states (in a speech, interview, press conference, or verified social media) that he has fired or decided to fire the person;
- The White House officially announces termination;
- Sends written communication to the person informing them of termination;
- Initiates formal legal proceedings for removal
The following do NOT qualify:
- Statements that the person "should" resign or be fired;
- Expressions of dissatisfaction;
- Asking or pressuring for voluntary resignation;
- Stating the President is "looking into" whether he can fire the person;
- Statements by other officials unless directed by the President;
- Unsent letters ordering termination
This market resolves on the President's attempt to fire, not on whether such attempt is legally valid, successful, or results in the person leaving office.
