As of my last knowledge update in June 2024, there has never been an American pope in history. The current pope is Pope Francis (born in Argentina), and no U.S.-born cardinal has been elected pope thus far.
If you’re referring to a hypothetical scenario where an American is elected pope and JD Vance (or another U.S. official) attends the inaugural Mass, that would be a significant historic event. However, as of now, this situation is purely speculative.
