That was never the case. But Baker, who’d heard tell of disorder at the White House, asked me and Jim Cannon, another longtime aide, to interview staffers and find out what was going on. I thought it was rather a mess, but Jim was positively disturbed by what he had learned.

On his initiative, Jim wrote an internal memo questioning whether Reagan was physically or mentally fit to continue as president. The memo began with a shocking recommendation: “Consider the possibility that section four of the Twenty-Fifth Amendment might be applied.” That amendment, of course, specifies that the president may be removed if the vice president and a majority of the Cabinet declare him “unable to discharge the powers and duties of his office.”

The whole situation was quite surreal. Baker, however, took the matter firmly in hand. “We will see for ourselves whether there is any merit” to the memo, he said.

In his capacity as the new chief of staff, Baker organized a lunch meeting with Reagan in the Cabinet Room. While the topics were general in nature, all those present understood that we were meant to determine whether there was any reason to further consider the Cannon memo. We probed the president’s recollection of Iran-Contra and asked ourselves if he demonstrated the capacity to lead the country over the next two years. (Jim was not in attendance.)

At the end of the lunch session, we reassembled in Baker’s office down the hall from the Oval Office. He began the discussion, stating that in his opinion the president was fully engaged: His statements on Iran-Contra were consistent with earlier statements and his health was not an issue. None of us disagreed. The issue raised in the Cannon memo on the Twenty-Fifth Amendment ended at that very moment.

In Landslide: The Unmaking of the President, 1984–1988, the journalists Doyle McManus and Jane Mayer published information on the Cannon memo. They noted that the Baker team “briefly considered invoking the Twenty-Fifth Amendment to relieve President Reagan of power.” The operative word is briefly. If there had been any serious consideration, the country and the world would have known.

Although nothing came of Jim’s memo, things were done in the right way. He didn’t deliver an anonymous, self-righteous, and self-justifying op-ed to a national newspaper. He shared his concerns with the people who could act if there was truly anything to worry about, and then he let the matter go.

I keep in my office a framed copy of my appointment as assistant to the president. It stated that I would serve “at the pleasure of the president” and that I would perform my duties with “integrity, prudence and ability.” I took that description seriously. If I had thought that these obligations were in conflict because the president was unfit—if I had disagreed with Baker’s verdict— I would have walked out.
