Since that is a slightly older article, it also happened under Joe Biden.

It also should have happened under Trump’s first term, but he’s a whiny bitch so it didn’t.

For fun the most common cause of “incapacitated” in these cases is for a colonoscopy.

It’s also worth clarifying that the 25th Amendment in these cases isn’t automatic. The President essentially drafts a letter and then power is returned to them after.

However in the case of the President being kidnapped, the Cabinet & Vice President could also declare incapacity and the VP would take over.
