(CNN) In late June 2017, President Donald Trump huddled with Ivanka Trump, Jared Kushner and then-communications aide Hope Hicks to figure out how to handle the fact that news of a June 2016 meeting between several Russians and his three top campaign officials (including Kushner) was about to break. Hicks warned that the story would be a big deal -- Trump operatives meeting with Russians with the promise of "dirt" on Hillary Clinton looked very bad, even if there was nothing illegal in it. Kushner disagreed, dismissing the story.

Then this happened, according to Mueller's report: "The President did not want to talk about it and did not want the details."

The back-and-forth is part of almost 300 pages of documents detailing witness testimony in special counsel Robert Mueller's probe into election interference unsealed -- at the request of CNN and Buzzfeed -- on Monday night. And it's hugely revealing about the way in which Trump deals with realities that he either doesn't like or make him uncomfortable: He buries his head in the sand.

Remember what we are talking about here: Kushner, Donald Trump Jr. and Paul Manafort met with a group of Russians in June 2016 at Trump Tower. According to publicly released emails, Don Jr. agreed to the meeting after an intermediary promised that the Russians had dirt on Hillary Clinton; it "would incriminate Hillary and her dealings with Russia and would be very useful to your father," wrote the intermediary. Replied Trump Jr. : "If it's what you say I love it especially later in the summer."

The eventual meeting, according to Trump Jr., was a nothing burger -- and ended quickly.
