Some of the anecdotes relayed in the upcoming Michael Wolff book have ignited a public discussion about President Trump’s mental fitness. But that question was being asked privately long before the book excerpts started making the rounds. “Lawmakers concerned about President Donald Trump’s mental state summoned Yale University psychiatry professor Dr. Bandy X. Lee to Capitol Hill last month for two days of briefings about his recent behavior.” From Politico: Washington’s growing obsession: The 25th Amendment.

+ “After more than a year of considering Trump’s behavior through the lens of the cognitive sciences, I don’t think that labeling him with a mental illness from afar is wise.” But there’s currently no official way to really evaluate a sitting president from up close. The Atlantic’s James Hamblin with a very interesting explanation of why there should be: Is Something Neurologically Wrong With Donald Trump?

+ Meanwhile, about that book… Trump’s lawyers are seeking to block its release, and Steve Bannon insists he still thinks Trump is “a great man.” And from Vox: The new book seems juicy. But what should we believe?

+ In other news from the executive branch, the US has suspended security aid to Pakistan, and on Wednesday, President Trump dissolved his sham commission that was investigating imaginary voters committing a crime that never took place.
