Stefan SiegertHistorically the leading reason for invoking the 25th amendment was colonoscopy, and removal of malignant growth from US presidents' butts.
The vice president temporarily assumed power in these cases. The US even had a female president for 1 hour and 25 minutes in 2021.
Unfortunately there is no clause in the 25th for what happens when the malignant object in the president's rectum is the vice president himself.
