If you want a perfect example of why his attorneys don’t want him to testify for Robert Mueller, listen to Trump talking to reporters after a meeting with Kim Jong-Un’s chief deputy at the White House, specifically when asked about a letter he delivered from Kim himself. In the space of 8 minutes, he lied and then admitted to the lie, all while appearing to be utterly oblivious to it.
“That letter was a very nice letter,” Trump said at a White House news conference. “Oh, would you like to see what was in that letter. Wouldn’t you like? How much? How much? How much?”
When a journalist asked whether the president could “just give us the flavor of what the letter said,” Trump said, “It was a very interesting letter. At some point, it may be appropriate and maybe I’ll be able to give it to you, maybe.”
Okay, so he must have read the letter to declare it interesting and act as though it was a really big deal that he knew what was in it but the reporters didn’t. But then mere moments later:
“I haven’t seen the letter yet,” the president said. “I purposely didn’t open the letter. I haven’t opened it. I didn’t open it in front of the director. I said, ‘Would you want me to open it?’ He said, ‘You can read it later.’ I may be in for a big surprise, folks.”
And it’s all on video, of course. This is why they know he’ll screw up under questioning. He literally just opens his mouth and says anything that comes to mind, without even a moment’s consideration for what is true or even what is strategically smart. He has the worst case of verbal diarrhea I’ve ever seen. He isn’t even capable of telling the truth except by accident. And yet he has an almost supernatural confidence in his own ability to talk his way out of anything. This is why I continually refer to him as a carnival barker.
