First American pope elected and will be known as Pope Leo XIV

> "Cardinal George of Chicago, of happy memory, was one of my great mentors, and he said: 'Look, until America goes into political decline, there won't be an American pope.' And his point was, if America is kind of running the world politically, culturally, economically, they don't want America running the world religiously. So, I think there's some truth to that, that we're such a superpower and so dominant, they don't wanna give us, also, control over the church."

He wasn't a Trump appointee. https://en.wikipedia.org/wiki/Francis_George

"Robert Barron, bishop of the Diocese of Winona–Rochester in Minnesota, was appointed less than a week ago by President Trump to the new White House Commission on Religious Liberty."

Honestly it looks like we've got a HNer quoting a journalist quoting a bishop quoting a cardinal.

The cardinal who said 'until America goes into political decline, there won't be an American pope' died in 2015 (i.e. before Trump's first term)

The bishop who quoted them does hold the post you mention - but they didn't originate the quote, they just quoted it.
