WASHINGTON >> Donald Trump has had as many as seven private phone calls with Vladimir Putin since leaving office and secretly sent the Russian president COVID-19 test machines during the height of the pandemic, Bob Woodward reported in his new book, “War.”

The revelations were made in the famed Watergate reporter’s latest book, which also details President Joe Biden’s frustrations with Israeli Prime Minister Benjamin Netanyahu and Saudi Crown Prince Mohammed bin Salman ‘s assortment of burner phones. The Associated Press obtained an early copy of the book, which is due out next week.

Trump denied the reporting in an interview with ABC News’ Jonathan Karl. “He’s a storyteller. A bad one. And he’s lost his marbles,” Trump said of Woodward.

Trump had previously spoken to Woodward for the journalist’s 2021 book, “Rage.” Trump later sued over it, claiming Woodward never had permission to publicly release recordings of their interviews for the book. The publisher and Woodward denied his allegations.

• Here is more from the new book:

Trump has had multiple calls with Putin since his White House term ended.

Woodward reports that Trump asked an aide to leave his office at his Florida resort, Mar-a-Lago, so that the former president could have a private call with Putin in early 2024. The aide, whom Woodward doesn’t name, said there have been multiple calls between Trump and Putin since Trump left office, perhaps as many as seven, according to the book, though it does not detail what they discussed.

Steven Cheung, Trump’s communications director, said none of the stories in Woodward’s books are true.

U.S. intelligence agencies later determined that Russia had meddled in the 2016 election to help Trump, though an investigation by special counsel Robert Mueller found no conspiracy between the Trump team and Russia. In 2018, Trump publicly questioned that finding following an in-person meeting with Putin in Helsinki.

In recent years, Trump has criticized U.S. support for Ukraine as it fights off Russia’s invasion. He has said Ukraine should have made concessions to Putin before Russia invaded in 2022. He also previously touted his good relationship with Putin and called the Russian leader “pretty smart” for invading Ukraine.

• Trump sent COVID-19 test machines to Putin for his personal use

Woodward reports that Trump sent Putin COVID-19 test machines for his personal use as the virus began spreading in 2020.

Putin told Trump not to tell anyone because people would be mad at Trump over it, but Trump said he didn’t care if anyone knew, according to the book. Trump ended up agreeing not to tell anyone.

The book also details Biden’s complicated relationship with Netanyahu as well as private moments when the president has been fed up with him over the Israel-Hamas war.

Biden’s “frustrations and distrust” of Netanyahu “erupted” this past spring, Woodward writes. The president privately unleashed a profanity-laden tirade, calling him a “son of a bitch” and a “bad f guy,” according to the book. Biden said he felt, in Woodward’s accounting, that Netanyahu “had been lying to him regularly.”

•Biden criticized Obama’s handling of the Russian invasion of Crimea.

The book details Biden’s criticism late last year of President Barack Obama’s handling of Putin’s earlier invasion of Ukraine, when Russia seized Crimea and a section of the Donbas in 2014, at a time when Biden was serving as the Democrat’s vice president.

“They f——- up in 2014,” Woodward wrote that Biden said to a close friend in December, blaming the lack of action for Putin’s actions in Ukraine. “Barack never took Putin seriously.”

Biden was angry while speaking to the friend and said they “never should have let Putin just walk in there” in 2014 and that the U.S. “did nothing.”

Biden regrets choosing Garland as attorney general

Woodward reports Biden was privately furious with Attorney General Merrick Garland for appointing a special counsel to investigate Biden’s son Hunter in a tax-and-gun prosecution.

“Should never have picked Garland,” Biden told an associate, according to Woodward.

The journalist did not name the associate.
