Write down the names of everyone you know that voted for this, and forever hold them responsible until they take their last breath…

According to two sources familiar with the conversation, Trump vented to his longtime security chief, Keith Schiller, “I hate everyone in the White House! There are a few exceptions, but I hate them!” (A White House official denies this.) Two senior Republican officials said Chief of Staff John Kelly is miserable in his job and is remaining out of a sense of duty to keep Trump from making some sort of disastrous decision. Today, speculation about Kelly’s future increased after Politico reported that Kelly’s deputy Kirstjen Nielsen is likely to be named Homeland Security Secretary—the theory among some Republicans is that Kelly wanted to give her a soft landing before his departure.

One former official even speculated that Kelly and Secretary of Defense James Mattis have discussed what they would do in the event Trump ordered a nuclear first strike. “Would they tackle him?” the person said. Even Trump’s most loyal backers are sowing public doubts. This morning, The Washington Post quoted longtime Trump friend Tom Barrack saying he has been “shocked” and “stunned” by Trump’s behavior.

While Kelly can’t control Trump’s tweets, he is doing his best to physically sequester the president—much to Trump’s frustration. One major G.O.P. donor told me access to Trump has been cut off, and his outside calls to the White House switchboard aren’t put through to the Oval Office. Earlier this week, I reported on Kelly’s plans to prevent Trump from mingling with guests at Mar-a-Lago later this month. And, according to two sources, Keith Schiller quit last month after Kelly told Schiller he needed permission to speak to the president and wanted written reports of their conversations.

Several months ago, according to two sources with knowledge of the conversation, former chief strategist Steve Bannon told Trump that the risk to his presidency wasn’t impeachment, but the 25th Amendment—the provision by which a majority of the Cabinet can vote to remove the president. When Bannon mentioned the 25th Amendment, Trump said, “What’s that?” According to a source, Bannon has told people he thinks Trump has only a 30 percent chance of making it the full term.
