15 U.S. presidential mysteries that were never solved

Not even presidents of the United States are immune to suspicious circumstances or curious conundrums.

From Congressional records, we know John Quincy Adams believed the earth was hollow. If only there were Congressional records to shed light on whether Harry S. Truman, the 33rd US President, believed that outer-space aliens landed in Roswell, New Mexico… or whether he ordered a cover-up of all evidence of such a landing. What we do know is that in July 1947, the military actually announced that a UFO had crash-landed in the Roswell desert, and the next day they said, sorry, nope, that didn’t actually happen. Somewhere in between, President Harry S. Truman is believed to have turned up in Roswell to examine the crash site. The question remains: Did he orchestrate what may be American history’s most massive UFO cover-up?

Roswell isn’t the only place conspiracy theorists believe aliens have landed – another is Area 51 in Nevada, which is just one of 10 forbidden places nobody will ever be able to visit.

Between February 1971 and July 1973, US President Richard M. Nixon secretly recorded 3,700 hours of conversations he wasn’t supposed to be recording, including those that became the basis of the Watergate scandal. When the existence of the tapes became public knowledge during that scandal, it was quickly discovered that 18-and-a-half minutes of a conversation between Nixon and his chief of staff, Bob Haldeman, was nothing more than audio feedback. Multiple attempts over the years to recover what’s come to be known as the “missing” audio have proved fruitless, and to this day no one knows for sure what Nixon and Haldeman were discussing. Based on the audio that’s NOT missing, there’s every chance the missing audio would have been extremely prejudicial.

On August 2, 1923, US President Warren G. Harding dropped dead as his wife, Florence, read him an article from The Saturday Evening Post. A serial philanderer, Harding had been warned by doctors that his ticker might not stand up to all the excitement, but Florence’s refusal to allow an autopsy gave rise to speculation she had poisoned him. Another theory, based on a review of Harding’s deteriorating health in the days leading to his death, is that America’s 29th president, at the age of 57, died of plain old ordinary heart failure.

In October 1919, US President Woodrow Wilson suffered a stroke that was kept secret for another four months. Even then, no official statement was made as to Wilson’s health or his ability to discharge his duties and powers as president. After a while, people became suspicious that America’s 28th president wasn’t “all there” and that his wife, Edith, might actually be running the country. In fact, she most likely was – and the first woman to do so – but this was kept a secret from the American public until years after Woodrow’s death.

James Buchanan is the only bachelor president in US history. While he had his niece act as First Lady, his long-term “roommate” was a man. To some, this begs the question: Was Buchanan, sworn into office in 1857, America’s first gay president? To others, there’s no question. That includes the historian Jim Loewen, who maintains Buchanan was not only gay but that his sexual orientation wasn’t even a secret back in the day. There’s no first-person evidence to prove this, since Buchanan’s personal correspondence was destroyed upon his death (at Buchanan’s own request).

John F. Kennedy’s assassination continues to be shrouded in secrecy and unanswered questions and one reason we may never definitively know what really happened is that sometime after JFK’s autopsy, his brain went missing. Consequently, any questions that came up as a result of the investigation run by the House Assassination Committee, whose questions might have required investigators to take a new look at JFK’s brain, are effectively unanswerable. Forever. So who took JFK’s brain. And why?

No one disputes that on April 12, 1945, US President Franklin D. Roosevelt died of a stroke. What’s mysterious is whether his stroke was the result of coronary artery disease… or metastatic cancer that had spread to his brain. Lots of evidence points to cancer, including his general frailty and weight loss at the end of his life, and a spot on his forehead that some medical professionals identify by sight as melanoma, and which disappeared from photos of America’s 32nd president after 1940. But the answers continue to elude us to this day. Another mystery surrounding Franklin D. Roosevelt was the bomb shelter he had built at the White House… find out more about it and other secret chambers inside famous landmarks.

James A. Garfield is thought to have been the second of four presidents to have been assassinated by gunshot. But the passage of time has gradually shed light on what really killed Garfield, who was lucid after the July 2, 1881 shooting and lived for another 79 days. Turns out it probably wasn’t the bullet, but the gross ineptitude of the doctor attending to him. Unable to locate the bullet, the doctor probed Garfield’s wound several times a day with unsterilised fingers and makeshift devices, until Garfield succumbed to sepsis. An autopsy confirmed the bullet alone would not have killed him.

Grover Cleveland, the USA’s 22nd and 24th president, didn’t die in office, but his whereabouts in June 1893 were a bit of a mystery. Officially, Cleveland had “gone fishing” for a few days when in truth, he was having oral surgery to remove a tumour from his palate. Later that summer, the story leaked, but Cleveland denied it. In 1908, after Cleveland died of a heart attack, Cleveland’s doctor confirmed the surgery but remained vague about the diagnosis. In 1980, a re-examination of the tissue removed from Cleveland’s palate revealed he did, in fact, have a non-fatal form of cancer.
