Former President Donald Trump loves to tell grandiose tales, especially to bolster a particular point, though sometimes the details of his stories aren't 100% correct or even verifiable.

That may be the case with a story Trump told recently about a near-crash landing in a helicopter ride decades ago with former San Francisco Mayor Willie Brown, who he alleged said "terrible things" about his former girlfriend, Vice President Kamala Harris, according to PolitiFact.

There's one major problem with Trump's account of the incident, however -- namely that Brown has fervently denied that he was ever in a helicopter with Trump, much less experienced an emergency landing, and that he never spoke negatively to Trump about Harris, whom he dated in the mid-1990s and admittedly helped boost her then-nascent political career.

Trump's tale about a helicopter ride with Willie Brown

During a recent press conference, former President Trump was asked about the prior relationship between then-attorney Harris and then-California Assembly Speaker Brown, and Trump responded with his recollection of a concerning helicopter ride with Brown.

"I went down in a helicopter with him. We thought maybe this was the end," Trump said. "We were in a helicopter going to a certain location together, and there was an emergency landing. This was not a pleasant landing. And Willie was -- he was a little concerned."

"So I know him, but I know him pretty well. I mean, I haven’t seen him in years," the former president added of the former mayor. "But he told me terrible things about her. But this is what you’re telling me, anyway, I guess. But he had a big part in what happened with Kamala. But he -- he, I don’t know, maybe he’s changed his tune. But he -- he was not a fan of hers very much, at that point."

Brown denies Trump's story

According to PolitiFact, former Mayor Brown has been adamant that former President Trump's story is false, or at least has some of the details mixed up, in that he has no recollection of their ever being on a helicopter together or of speaking ill about his former love interest.

"I’ve never been on a helicopter with Trump," Brown told the San Francisco Chronicle and similarly told local outlet KRON that Trump had engaged in "creative fiction" with his tale of an emergency landing.

In an interview with CNN, Brown insisted that Trump's details in the story were "obviously wrong" and further opined, "He is trying his best to get some way to degrade Kamala. There is no reason why her name ought to be mentioned anywhere near his lies, period."

Possible mix-up on timing and participants of helicopter flight?

PolitiFact noted that there had been some speculation that former President Trump may have confused former Mayor Brown with former California Gov. Jerry Brown, whom Trump did ride with, along with then-Lt. Gov. Gavin Newsom, in a helicopter while touring wildfire damage in 2018.

Except, the former mayor is black while the former governor is white, and CNN reported that both Brown and Newsom have said there was no emergency landing, nor any talk of Harris, during that particular flight.

There has also been some speculation that Trump may have mixed up the former mayor with another black California politician who did experience an emergency landing in a helicopter with the then-real estate mogul in the early 1990s, according to Politico.

That other politician is former state senator and Los Angeles city councilmember Nate Holden, who took an aerial tour of some of Trump's properties in New York and New Jersey ahead of a planned Trump development in L.A., and while Holden confirmed that the helicopter did suffer mechanical issues and was forced to make a hard landing, he denied that there had been any discussion of Harris, who was still a relatively unknown Bay Area attorney at the time.

Despite all of the pushback and denials, The Hill reported that Trump has doubled down on the Willie Brown helicopter story, suggested that he would provide documentary evidence of the flight, and even threatened to sue The New York Times and other media outlets over their fact-checks of his tale.
