No matter what happens, President Donald Trump won’t have the shortest tenure has U.S. president.

At the moment, Trump has served 118 days in office, as impeachment talk is in the air, at least slightly, after a report he told the former director of the Federal Bureau of Investigation to drop a probe into Trump’s former national security adviser.

The distinction for shortest tenure is held by William Henry Harrison, who died on April 4, 1841 after 31 days in office.

The conventional wisdom is that Harrison died of pneumonia after not wearing a coat or a hat during his inauguration. But the more likely story is that he contracted a bacterial disease though contaminated water. Washington at the time had no sewage system and the White House water supply was very near where some of the sewage flowed.

These days, Washington, D.C. has a sewer system, although when it rains, raw sewage still flows into the Potomac River.

James A Garfield had the next shortest presidency. He was assassinated on Sept. 19, 1881 after 199 days in office.

President Zachary Taylor has the third-shortest term. He died in office on July 9, 1850 after 491 days in office. Although Taylor died of an unidentified stomach illness after eating tainted cherries and milk, there were rumors at the time that he had been eliminated by political rivals.

Warren Harding died on August 2, 1923 after 881 days in office, to mark the fourth-shortest presidential tenure. Harding died of a heart attack in San Francisco as his wife, Florence Harding, was reading a newspaper to him. There were rumors that swirled around his death after a former Harding Administration official wrote a book saying that Harding had been poisoned by his wife.

Rounding out the top five is Gerald Ford, whose term lasted 895 days as he served the remainder of Richard Nixon’s term.
