"Peril," by Bob Woodward and Robert Costa, offers a political insight into the months before and after the 2020 election, including the COVID-19 pandemic, the Jan. 6 riot and the 2020 presidential campaign.
As it covers the inauguration of President Biden, the book reports that the Trump experience of that day – when he took off in Marine One to begin his journey to Mar-a-Lago ahead of the ceremony – was "full circle" from his own inauguration in 2017.
Woodward and Costa report that Trump and Obama drove from the White House to the Capitol, along with Sen. Roy Blunt, who was responsible for organising the inaugural celebration.
"What was your biggest mistake?" asked the president-elect to his predecessor.
Obama is then said to have stopped and looked back at Trump.
"I can't think of anything," he is said to have responded. Trump then changed the subject, and asked, "Is this the car you use all the time?"
The book has already made titles, in part for its reporting about how General Mark Milley was in communication with the Chinese to reassure them about fears of an attack during the chaos surrounding the Jan. 6 Capitol riot.
The book has exposed shocking details from inside the White House, including that General Mark Milley contacted Gen. Li Zuocheng of the People's Liberation Army to console him the U.S. was not going to suddenly attack China.
On Friday, he defended his calls to his Chinese counterpart as "perfectly within the duties and responsibilities" of his job as chairman of the Joint Chiefs of Staff.
The general was slammed by the former president and several conservatives for his conversations, including being accused of "treason" for violating the chain of authority.
Peril comes as a closing trilogy to Woodward's earlier publications Fear and Rage that report Trump's time in office.
Other key figures like former New York Mayor Rudi Giuliani make noticeable appearances again.
The book explained Trump's former lawyer going on several shows to keep his friend, only for Trump to call him a "baby" and tell him on the phone that "they took your diaper off right there," according to The New York Times.
Like Woodward's previous records, the artists surveyed more than 200 sources, and all live unnamed throughout.
