Three congressional Democrats have asked a psychiatrist at Yale School of Medicine to consult with them about forming an expert panel to offer the legislators advice on assessing President Trump’s mental health.

Yale’s Dr. Bandy Lee told STAT that over the last few weeks members of Congress or their staff have asked her to discuss how members might convene psychiatrists, psychologists, and other mental health professionals “to review the president’s mental health, and review it on a periodic basis.” The closed meeting is expected to take place in September, she said.
