The three phases that describe the relationship between the president and the media are:
1. Adversarial: In this phase, the president and the media are often in conflict, with the media being critical of the president's policies and actions.
2. Watchdog: In this phase, the media serves as a watchdog over the president, holding them accountable for their actions and policies.
3. Collaborative: In this phase, the president and the media work together to achieve common goals, such as informing the public about important issues or promoting the president's agenda.
