But Wednesday wasn’t the first time Biden has appeared to tell some rendition of this same story.
In April, Biden chronicled the same memory with his mother, but said it was asthma he got as a result, not cancer.
“This is the God’s truth. When you get in the car and there's a little frost on the window, turn on the windshield wiper, there'd be an oil slick, not a joke. I have asthma and 80 percent of the people who in fact we grew up with have asthma. That's what you call a fence line community.”
Biden has also been caught telling different renditions of the same story in the past when he has chronicled stories of his purported arrest as a young boy while defending civil rights. After that gaffe, Kessler gave Biden four “Pinocchios,” pointing out the president had told numerous versions of the same story in the past.

On Wednesday, besides the cancer gaffe, the president also called a male member of Congress a “she” and said Glasgow, Scotland is located England.
