Problem:
Congress, with Senator Diana Prince as a leading figure, is considering a national data breach notification law that would preempt the patchwork of 48 state laws currently in place. The proposed law aims to standardize breach notification requirements across the country but raises questions about what specific elements it should include, such as the types of personal information covered, the timing of notifications, and whether it should incorporate a risk-of-harm exception. As a policymaker, outline the key elements you would include in a national data breach notification law that preempts state laws. Should this law cover additional categories of personal information, and how should it address the risk-of-harm exception?
