(CNN) On Thursday night, Donald Trump did a 45-minute phone interview with Fox News' flagship face: Sean Hannity.

That, on its own, is, well, odd. The President of the United States spending 45 minutes on the phone with a conservative talk show host isn't something that happened ever before. And may not happen ever again. Also, sort of weird in that Hannity hosts a TV show and TV is a visual medium -- not exactly the preferred medium for an extended phone interview.

But it's not just that Trump did it that is so startling. (In fact, calling into cable shows has been a regular Trump practice since the 2016 campaign and even before). It's what Hannity and Trump talked about. I went through the most remarkable 45 lines from the 45-minute interview , but suffice it to say that it was a miasma of conspiracy theorizing, fact-free "analysis" and martyrdom.

"So, I really say, now we have to get down because this was a coup," Trump said at one point, referring to the probe into Russian interference in the 2016 election. "This was an attempted overthrow of the United States government."

At another, Trump said this: "This was a coup. This wasn't stealing information from an office in the Watergate apartments. This was an attempted coup."
