US President Donald Trump keeps repeating a falsehood about Osama bin Laden - perhaps in the hopes that the more he says it, the more people will believe it.

The president spoke about the late founder of al Qaeda on Sunday while aboard Air Force One, where he was accompanied by Sen. Lindsey Graham (R-S.C.) and reporters.

Trump spoke to the gaggle about Venezuelan President Nicolás Maduro, who was captured by U.S. forces and flown to New York City, alongside his wife, to face narco-terrorism charges. While talking about the deposed leader, the president pivoted to an astonishing claim about bin Laden.

"Lindsey mentioned bin Laden. Do you know I wrote about bin Laden one year before the attack in the World Trade Center and I said, you got to go after bin Laden?" Trump falsely claimed. "It was in my book and very few people want to say that, but it was in my book."

"You know that I think you`ve actually talked about it," he told a reporter. "But if they would have listened to me, they would have taken out bin Laden and you wouldn`t have had the World Trade Center tragedy."

Trump has made this claim numerous times over the years, despite many pointing out that no such mention is made in the book he`s referencing, called "The America We Deserve," which he published in 2000.

While Trump does mention bin Laden in the book and the potential for another terror attack that would be bigger than the 1993 bombing at the World Trade Center, he doesn`t specifically link the two together.

"One day we`re told that a shadowy figure with no fixed address named Osama bin Laden is public enemy number one, and U.S. jetfighters lay waste to his camp in Afghanistan," Trump wrote at the time. "He escapes back under some rock, and a few news cycles later it`s on to a new enemy and new crisis."

Back in 2019, Trump once again claimed that he never "gets any credit" for allegedly warning the U.S. about bin Laden back in 2000 (though the leader was placed on the FBI`s Ten Most Wanted Fugitives list in 1999).

"In that book about a year before the World Trade Center was blown up, I said, ‘There`s somebody named Osama bin Laden. You`d better kill him or take him out,`" he said during a press conference where he announced the death of ISIS leader Abu Bakr al-Baghdadi.

"Let`s put it this way - if they would have listened to me, a lot of things would have been different," Trump said at the time.
