Moscow, Russia - The Kremlin recently responded to claims that Donald Trump sent President Vladimir Putin Covid-19 tests during the pandemic.

According to CNN, Kremlin spokesperson Dmitry Peskov told reporters on Thursday that Trump indeed "sent us several samples of test kits" but did not clarify whether they were specifically for Putin.

Peskov explained that the tests were sent at the beginning of the pandemic, when things were "difficult for all countries."

"Initially, all countries tried to exchange aid shipments with each other," Peskov continued.

"At that time, we sent a shipment of ventilators to the United States, and the Americans sent us several samples of test kits, as those were practically unique items.

"Many countries were doing the same," he added.

The admission confirms a claim made by journalist Bob Woodward in his upcoming book, in which he reported Trump sent the tests to Putin, who urged the president not to "tell anybody because people will get mad at you, not me."

The Kremlin's account contradicts Trump's, as the former president swiftly denied the claim and called Woodward "a storyteller" who has "lost his marbles."

His presidential campaign also shared a statement describing the claims as "made-up stories" from "a truly demented and deranged man."

Woodward's book, which is titled War, will be released on October 15, just 21 days before the presidential election on November 5.
