What you are dealing with with Donald Trump in terms of how he promotes things that are not true is something different than we have ever seen with a president.

Unfounded, not based in fact or reason, with no evidence to support them.

These are bold face lies.

His idea of the truth is fast and loose. He's the liar. He's the one who has to be held accountable.

Hello and welcome to Trumpcast, the show about the man who put the me back in Memorial Day. Donald Trump. I'm Jacob Weisberg.

In case you missed it, I'm referring to Donald Trump's weekend tweet where he said that those who died for our country would be happy and proud of how well America is doing under his leadership.

To which I say, bleh, what a disgusting, solipsistic, dishonest thing for a president to say. I mean, really, Jesus Christ.

But you can't call it a lie. For one thing, it has no factual content. Dead people would be happy. They're dead. It's an absurd proposition.

But other things Trump said over the holiday weekend look a lot more like conventional lies. For example, he accused the New York Times of quoting a senior White House official who doesn't exist on North Korea.

Trump called that person a phony source. That phony source, who said it wouldn't be easy to have the North Korea summit in a couple of weeks after all, was a national security council official named Matt Pottenger.

He briefed 50 reporters on background just a few steps away from the Oval Office. Trump also falsely blamed Democrats for a horrible law separating immigrant children from their parents.

In fact, that's his own policy. He just announced it. Maggie Haberman, the incredibly well-sourced New York Times White House reporter, caught a load of flak for calling these demonstrable falsehoods on Twitter.

Let's call lie a lie. A lot of angry people responded suggesting that Haberman and the Times were somehow going soft on Trump.

Haberman responded that a lie requires conscious intent. And in this instance, it was lacking. Should journalists be using the L word a lot more often? Or should we just let lying dog sleep?

I'll be back to discuss it with the encyclopedist of Trump's lies, Daniel Dale of Toronto Star. But first, leaking to the press, the Trump administration just can't get its own officials to stop.

Okay, Sean, have a seat. Okay. Okay, cool. So as you know, Sarah Huckabee Sanders gave that big speech to everyone here in the communications department about the problem with leaking.

Yes, bad. But the problem hasn't stopped. So I'm just giving her a hand sitting down with everyone one on one and just making sure that everyone understands that leaks need to stop. Yeah, yeah, well, I'm glad, you know, I respect that.

Hey, real quick, Sean. Would you buy putting your phone down? Putting your phone down. Okay, let me just look at that phone real quick. Yeah, sure what? You're just, okay, you're just writing down exactly what I'm saying.

Yeah, yeah, yeah, no, I'm going to, I'm calling Maggie Haberman at three. So I just wanted to get exactly what you said. Okay, well, this is actually exactly what when I'm talking about. So you're leaking this conversation about leaks. Oh, that's, so that's the kind of thing that you guys are upset about. Exactly. So, okay. So go ahead. Yeah, just put your phone down. Perfect. So as a member of this administration, it's really important that Sean, why did you just open your laptop?

Oh, I just wanted to write down exactly what you're saying because I'm, I'm pasting it into the body of an email that I'm sending to Chris Hayes. He's all in. So, okay, yeah, okay, I'm just going to close that laptop. Again, I really feel like you're not getting the point here. So this administration is crumbling a little bit because of the, that's a hot quote, this administration is crumbling and inside source. That's going to be good. Wait, why do you have a bird cage with you? This is my carrier pigeon. He flies to Jim Acosta.

Oh, so I'm just tying this parchment. Okay, don't I don't want to hurt the bird. But I'm going to take the bird from you. Okay.

And okay, I got the bird. I guess how will I leak?
