The gaffe came during a speech in Iowa, while the 76-year-old Biden was comparing the years of his young adulthood to the current day.

“Just like in my generation, when I got out of school, when Bobby Kennedy and Dr. King had been assassinated in the ’70s, the late ’70s when I got engaged … ,” Biden recalled.

But King and Kennedy were murdered in 1968, about two months apart.

It was just the latest in a series of slip-ups for the Democratic Party’s 2020 presidential frontrunner.
