On CNN this morning, David Gregory, speaking of President Trump’s tweeting—and specifically, those from this weekend criticizing the judge who blocked his executive order on immigration—said: “he sounds like an old man sitting on his porch yelling at somebody to get off his lawn.”

Added Gregory: “you’ve had in the first 18 days, successive weekends where he has completely derailed what his administration is trying to do with a kind of personal indulgence by attacking people personally, launching an attack on the separation of powers. But what it really comes down to is this obsession with himself, and I think that’s going to start to wear thin.”

In addition to the tweet cited in the clip, Trump issued another over the weekend calling James Robart, who issued the order, a “so-called judge.” Do Trump’s tweets reflect a considered strategy to disrupt the system, or can they be counterproductive?

ALISYN CAMEROTA: And David Gregory, as I understand it, now, because it is going to through the court system and may go as high as the Supreme Court, all of Mr. Trump’s tweets become part of the record. And they could end up hurting him. Here’s one tweet that is significant that he sent out yesterday: “Just could not believe a judge would put our country in such peril. If something bad happens blame him and court system. People pouring in. Bad!”

Well, first, people are not pouring in. Unchecked. That’s not our system. But what do his tweets now mean now that this is in a different arena?

DAVID GREGORY: I mean, honestly, he sounds like an old man sitting on his porch yelling at somebody to get off his lawn. I mean, that’s just the reality. I think we’ll do well to start separating his rants as President of the United States from the actions that the administration is taking. They are appealing; they are following the procedures they want to.

But now you’ve had in the first 18 days, successive weekends where he has completely derailed what his administration is trying to do with a kind of personal indulgence by attacking people personally, launching an attack on the separation of powers. But what it really comes down to is this obsession with himself, and I think that’s going to start to wear thin.
