• Who killed Washington Post columnist Jamal Khashoggi inside the Saudi embassy in Turkey? Maybe "rogue killers," says the president.

• And maybe, if it was "rogue killers," the president won't have to follow through on the "severe punishment" he promised if it turned out the Saudi leader ordered Khashoggi's killing.

• Why does Trump now think it might have been "rogue killers"? Because the King of Saudi Arabia got on the phone with Trump and "firmly" denied any involvement. As Chris Cillizza writes at CNN:

That believe-the-denial approach, of course, only holds for when Trump wants or needs to believe the person doing the denying... Trump swerves between taking your word for it and absolutely refusing to take your word for it even when your word is backed up by lots and lots of evidence. His approach to allegations is entirely situational. He believes denials when it suits him — even when it seems incredulous for him to do so. And he refuses to believe denials when it plays into some sort of broader conspiracy theory he has either hatched or is peddling.

• Related: "Donald Trump finally just said it," Laura McGann writes at Vox. "He doesn’t care if Christine Blasey Ford was telling the truth." As Trump said recently on 60 Minutes, nothing else really matters to him except this: "We won."

• Oh, and even though UN scientists say we're in big trouble because of climate change, Trump still thinks it's all a hoax. And even if it's not a hoax, he told 60 Minutes, "it'll change back again."

• You, being a rational person interested in empirical evidence, might prefer to believe the video evidence of Trump promising to give $1 million to the charity of Elizabeth Warren's choice if she proved her Native American ancestry.

But take note: Trump now says he didn't say what he said. Also: "Who cares?"
