Former President Trump has held at least seven private conversations with Russian strongman Vladimir Putin since leaving office, according to a forthcoming book by journalist Bob Woodward. Trump also gave Putin scarce COVID-19 testing kits for his personal use while he was president, the venerable Washington Post scribe reveals in his new book, “War.” “Trump was the most reckless and impulsive president in American history and is demonstrating the very same character as a presidential candidate in 2024,” Woodward writes in “War,” which is set to hit store shelves next week. Woodward quotes an unnamed top Trump aide as the source for his claim that the two leaders spoke at least seven times since 2021. The former president ordered the aide out of a room at his Mar-a-Lago in early 2024 and told him he was planning to call Putin, Woodward writes in the book that hits shelves Monday. It’s not known what Trump and Putin may have discussed during the secret chats. Trump has repeatedly bragged of his cozy ties to the Russian dictator and called Putin “pretty smart” for invading Ukraine. Critics say he would end aid to Kyiv and force Ukraine to surrender huge swaths of its territory to appease Putin.

But experts say it is rarely charged because it is difficult to prove. The close relationship between the two leaders is underlined by Trump’s decision to give several COVID testing devices to Putin at a time when the pandemic was sweeping the world and the famously germaphobic Putin was scared of being infected. Woodward reports that Putin warned Trump to keep the gift under wraps to protect political blowback. “Don’t tell anybody you sent these to me,” Putin told Trump. “I don’t care. Fine,” Trump replied. “No, no. I don’t want you to tell anybody because people will get mad at you, not me,” Putin responded. “They don’t care about me.” Vice President Kamala Harris, Trump’s opponent in the November election,  denounced the former president over the revelations in an interview with Howard Stern on Tuesday. “(It’s) just the most recent stark example of who Donald Trump is,” Harris said. Trump denied all the revelations in the Woodward book through a campaign spokesman. “None of these made-up stories by Bob Woodward are true and are the work of a truly demented and deranged man who suffers from a debilitating case of Trump Derangement Syndrome,” Steven Cheung, the spokesman, said in a statement. The book, Woodward’s fourth tell-all since Trump first won the White House in 2016, also reveals spicy details about Biden. The president dropped f-bombs in deriding both Putin and Israeli Prime Minister Benjamin Netanyahu in separate conversations with aides. Biden also reportedly told aides he regretted appointing Attorney General Merrick Garland because of the way he handled the case of his son, Hunter.
