One excerpt from the book portrayed Hunter Biden as wielding particular influence over his father, engaging with the White House in a manner that made even some of the former president’s staff, such as Siskel, uneasy.

The authors wrote that Siskel was shocked and dismayed when he discovered that Hunter Biden was on a White House video call with the then-president discussing whether his father should provide an on-camera statement to the Supreme Court’s July 2024 decision that former presidents have some immunity from prosecution.

“Suddenly an unidentified voice piped up from Biden’s screen and recommended an Oval Office address,” the book reads. “At first, some aides had no idea who was speaking. It soon became clear the voice belonged to Hunter Biden, who the White House staff had not known was on the call. Siskel expressed some concern about the appearance of using the Oval Office.”

“Hunter snapped back: ‘This is one of the most consequential decisions the Supreme Court has ever made.’ He said his father had every right to use the powerful imagery of the Oval Office to deliver that message,” the book continues. “They later settled on the Cross Hall, the long hallway on the first floor of the White House. After the call ended, Siskel told colleagues. Hunter’s presence was inappropriate.”

The new book also alleges that Hunter Biden attempted to pressure the Democratic National Committee into paying massive legal fees for the federal tax and gun charges he faced last year.

During an ABC interview over the weekend, Dawsey said that while doing research for the book, Hunter emerged as a pivotal figure in his father’s White House, including in helping him campaign for reelection.

“What we found out over the course of reporting for our book is Hunter Biden (was) a major figure in the president’s orbit,” the Wall Street Journal reporter told the outlet. “He was often on these calls, he would pipe in to calls, he was helping him make campaign decisions, and the president was very concerned about his son. It was one of the things that was an albatross on him as he tried to run for reelection.”

The release of 2024: How Trump Retook the White House and the Democrats Lost America, comes after Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again, written by CNN’s Jake Tapper and Axios’s Alex Thompson, provoked a similar uproar when it was published in May.

Both books center on allegations that Biden’s top allies attempted to cover up his decline and helped him attempt to run for another term, despite evidence that he suffered from severe cognitive troubles in recent years.
