Donald Trump still wrongly thinks President Barack Obama wiretapped him in Trump Tower: Lewandowski book

Corey Lewandowski's new book revealed that President Donald Trump still believes that former President Barack Obama wiretapped him in Trump Tower, Maggie Haberman reported for the New York Times.

Trump made the allegation just months after taking office in 2017.

According to an interview Lewandowski and David Bossie, Trump still believes what he said on Twitter, despite mountains of evidence to the contrary.

"Two informal advisers to President Trump aims to buttress his claim that he is the victim of a vast conspiracy inside the federal government," Haberman wrote for The Times.

Neither Trump nor his allies have offered any proof of the claims and former FBI Director James Comey testified under oath that he has no information to support the president's claim. Trump's own Justice Department also was unable to find anything to substantiate the claim.

Former Trump campaign chair Paul Manafort was wiretapped, but not during the time that he was serving in Trump's campaign and not through Trump himself at Trump Tower.
