Biden, 76, has long been plagued by health issues. In 1988, he suffered an aneurysm that burst and required him to undergo emergency surgery. The then-senator was so close to death that a Catholic priest began preparing to administer the sacrament of last rites.

Months later, surgeons clipped a second aneurysm before it burst. Biden then took a seven-month leave from the Senate following the surgery. He has described the operation as “they literally had to take the top of my head off.”

Doctors removed a benign polyp during a colonoscopy in 1996. In 2003, Biden had his gallbladder removed. He also suffers from asthma and allergies, and takes a prescription drug to lower his cholesterol. He has also taken medication for an enlarged prostate.

Biden hasn’t disclosed his medical history since 2008 when doctors found he had an irregular heartbeat.

Biden has also raised eyebrows for the increasing number of verbal blunders he has made so far on the 2020 campaign trail, the schedule of which has been markedly lighter than his main rivals.

Those close to Biden nevertheless maintain that he is "a picture of health," according to a former aide who spoke to the Washington Examiner in April. Were he to win the 2020 presidential election, he would be the oldest president ever to be inaugurated.
