A new report from the Daily Beast’s Asawin Suebsaeng claims that President Donald Trump got into a bizarre argument last year during a meeting with Vietnam veterans over the classic war movie “Apocalypse Now.”

According to Suebsaeng’s sources, the meeting between Trump and several Vietnam veterans was arranged by estranged former aide Omarosa Manigault-Newman, who at the time served as a liaison between the president and veterans’ organizations.

During the meeting, a dispute broke out over whether Robert Duvall’s character in “Apocalypse Now” used napalm or Agent Orange against Vietcong forces. Apparently, Trump falsely believed that it was Agent Orange that U.S. forces used against the enemy, despite the fact that the movie’s single most famous line is Duvall’s character saying, “I love the smell of napalm in the morning.”

“Multiple people — including Vietnam War veterans — chimed in to inform the president that the Apocalypse Now set piece he was talking about showcased the U.S. military using napalm, not Agent Orange,” Suebsaeng reports. “Trump refused to accept that he was mistaken and proceeded to say things like, ‘no, I think it’s that stuff from that movie.'”

One veteran who was present at the meeting described it to Suebsaeng as “really f*cking weird.”
