This bill would establish a Commission on Presidential Capacity to Discharge the Powers and Duties of the Office to implement the 25th Amendment process for determining whether a president is mentally or physically unable to serve. The 17-member commission would include physicians appointed by congressional leaders, former high-ranking executive branch officials from both parties, and an independent chair, with members required to include at least some psychiatrists. When Congress directs the commission through a concurrent resolution, it would have 72 hours to examine the president for conditions including physical illness, mental illness, drug or alcohol use, or any other impairment that prevents the president from executing their duties, and then report its findings to Congress within another 72 hours. The commission members would serve either until January 1, 2031 (initial appointees) or for four-year terms thereafter, with the first appointments required within 10 days of the bill's enactment. The bill specifies that the president's refusal to undergo examination and any disagreement by the vice president would be documented in the commission's report. Notably, the bill overrides privacy regulations under the Health Insurance Portability and Accountability Act to allow the commission to share medical information in its official report.
