MSNBC’s Joe Scarborough on Monday morning went to town on Donald Trump’s latest story involving an unnamed “sir,” a verbal habit of the former president that commentators have previously noted pretty much means he’s about to lie.

“It’s not even a good lie for Donald Trump,” said the anchor.

Over the weekend, Trump railed against the NATO military alliance at a campaign rally and claimed, “One of the presidents of a big country stood up and said, ‘Well sir, if we don’t pay and we’re attacked by Russia, will you protect us?’ I said, ‘You didn’t pay? You’re delinquent?’ He said, ‘Yes, let’s say that happened.’ No, I would not protect you. In fact, I would encourage them to do whatever the hell they want. You gotta pay. You gotta pay your bills.”

Scarborough highly doubted Trump’s version of the events.

“Nobody is saying that. What a jackass!” he said. “How stupid would you have to be in that audience to go, ‘Oh, well, did they really say that? That’s amazing. I can’t believe a big country president would say that.’ It’s just stupid.”

The “Morning Joe” cohost suggested Trump was “now so desperate to support [Russian President] Vladimir Putin and undercut America’s allies in Europe, he’s making up a ‘sir’ story?”

“It’s not even a good lie for Donald Trump. Like, this is you can tell he’s losing it,” he said, later adding it was the kind of story that even a third-grader would question.
