President Joe Biden has long had a habit of embellishing the details -- some would say lying -- to prove a point in the many anecdotes and stories he tells supporters during speeches and when speaking with reporters.

Biden did exactly that on three occasions in two days while campaigning in Pennsylvania when he got several details wrong in a tale he told about his uncle's death during World War II, according to ABC News.

The president was attempting to exploit his reverence for his uncle's heroic service as a contrast against the alleged disrespect his rival, former President Donald Trump, is said to have displayed during a 2018 trip to France when he ostensibly refused to go to an American cemetery filled with "suckers" and "losers" who fought and died in World War I -- a hotly disputed purported incident that Trump and many others who were there have vehemently denied.

Biden contrasts uncle's WWII service with alleged remarks from Trump

Wednesday afternoon, while addressing union steel workers in Pittsburgh, President Biden spoke about his visit earlier in the day to a World War II monument in Scranton that bore the etched name of city residents who died during the war, including his "Uncle Bosie," U.S. Army Air Corps 2nd Lt. Ambrose J. Finnegan Jr.

Biden claimed his uncle enlisted on the day after the Allied D-Day invasion of France -- June 6, 1944 -- and said that he flew single-engine reconnaissance planes in the Pacific theater, "And he got shot down in New Guinea, and they never found the body because there used to be -- there were a lot of cannibals, for real, in that part of New Guinea."

The president then mentioned his late son, Beau, who died of brain cancer that Biden adamantly insists is linked to his year-long service during the Iraq War and the toxic burn pits the U.S. military used to dispose of waste. He then referenced the disputed "suckers" and "losers" remarks from former President Trump years earlier and asserted of Trump, "That man doesn’t deserve to have been the Commander-in-Chief for my son, my uncle."

Claimed he enlisted after D-Day, shot down over New Guinea, eaten by cannibals

Just a few hours earlier, while speaking to reporters at the airport near Scranton, President Biden was asked about his visit to the war memorial and similarly claimed that his uncle had enlisted after D-Day and flew reconnaissance planes over New Guinea.

"He had volunteered because someone couldn’t make it. He got shot down in an area where there were a lot of cannibals in New Guinea at the time," Biden said. "They never recovered his body. But the government went back, when I went down there, and they checked and found some parts of the plane and the like."

"And what I was thinking about when I was standing there was when Trump refused to go up to the memorial for veterans in Paris, and he said they were a bunch of 'suckers' and 'losers,'" he added. "To me, that is such a disqualifying assertion made by a president -- 'suckers' and 'losers.' The guys who saved civilization in the 1940s -- 'suckers' and 'losers.'"

The third such incident came on Tuesday when Biden held a campaign event in Scranton and mentioned his plan to visit the war memorial to see his uncle's name and pay his respects, and again claimed that his uncle had enlisted after the D-Day invasion.

He also recounted the alleged "suckers" and "losers" incident with Trump and the cemetery in France and said of his rival, "Who the hell does he think he is? Who does he think he is? These were heroes. These soldiers were heroes, just as every American who has served this nation. Believing otherwise, that alone is disqualifying for someone to seek this office. Thank God I wasn’t standing next to him."

Official account doesn't match up with Biden's stories

According to ABC News, however, U.S. Army records show that 2nd Lt. Finnegan enlisted a few weeks after the Dec. 7, 1941 attack on Pearl Harbor -- not three years later after D-Day -- and he did not die while flying a single-engine reconnaissance plane, nor was he eaten by cannibals in New Guinea, as President Biden repeatedly implied.

Rather, official records show the Finnegan was a passenger on a transport plane that was forced to ditch itself into the Pacific Ocean off the coast of New Guinea "for unknown reasons." An incident report stated, "Both engines failed at low altitude, and the aircraft’s nose hit the water hard. Three men failed to emerge from the sinking wreck and were lost in the crash," and added of Finnegan, "He has not been associated with any remains recovered from the area after the war and is still unaccounted-for."

Pressed on the discrepancy between Biden's story and the official account, White House spokesman Andrew Bates dodged the issue and instead said in a statement that Biden was "proud of his uncle’s service in uniform" and that he "highlighted his uncle’s story as he made the case for honoring our 'sacred commitment ... to equip those we send to war and take care of them and their families when they come home,' and as he reiterated that the last thing American veterans are is 'suckers' or 'losers.'"
