 Senator, you just reminded me. When I was the youngest member of the White House Council staff for President Reagan, he underwent colon surgery. So Fred Fielding and Dick Hauser came over and they got the smartest guy in the office, who happens to be the Chief Justice of the United States now, John Roberts, to write up a memo on how to transfer presidential powers for a period of time certain and how to get them back so that George Bush became the first ever acting President of the United States pursuant to the 25th Amendment.
