ABC News reporter Jonathan Karl is out with a new book, Betrayal, which gives an account of the final days of former President Donald Trump's administration -- and includes some anonymous revelations by Trump's former staff.

In one section, Karl describes a dinner party at the DC home of Ivanka Trump and Jared Kushner on January 7, 2021. The entire evening, there wasn't a single mention of what had happened the day before when Trump's supporters ravaged the U.S. Capitol building, according to Karl's account.

"Among those who attended were Larry Kudlow and Brooke Rollins, who were still working as senior officials in the Trump White House. Kevin Hassett, who had served as one of Trump's top economic advisors until the summer of 2020, was also there. One of those who attended the dinner told me the conversation centered on the idea of creating a new think tank to promote free-market economics in a way that would appeal to Democrats," Karl's book revealed.

He noted that Kudlow "spoke wistfully" about a bygone era when Democrats supported Ronald Reagan's trickle-down economics.

"Remarkably, there was no mention of the fact that a mob had just stormed the Capitol days earlier, ransacking the offices of Democratic leaders and trying to prevent the certification of Joe Biden's election victory," the book continued. "There was no mention whatsoever—whatsoever—by Jared and Ivanka or any of their guests—of January 6."

The guest who spoke to Karl ironically called it "the elephant in the room." The GOP's symbol is an elephant.

In Michael Wolff's book Fire and Fury, Jared and Ivanka decided that they could ride the Trump coat tails all the way to Ivanka's own presidency.

"Balancing risk against reward," they "decided to accept roles in the West Wing over the advice of almost everyone they knew," wrote Wolff. "It was a joint decision by the couple, and, in some sense, a joint job. Between themselves, the two had made an earnest deal: If sometime in the future the opportunity arose, she'd be the one to run for president. The first woman president, Ivanka entertained, would not be Hillary Clinton; it would be Ivanka Trump."

In January, the Daily Mail reported that Donald Trump had no intention of attending the inauguration of incoming President Joe Biden. To "save her reputation" and her "promising political career," Ivanka decided that she would attend the event alone. However, the invitation didn't extend to her. It was only for former presidents.
