Flashback: Biden Says His Mother Used to Use Windshield Wipers to Wipe off Oil Slick and That’s Why He Got Cancer

TRANSCRIPT:

BIDEN: "And because it was a four-lane highway that was accessible, my mother drove us and — rather than us be able to walk. And guess what? The first frost, you knew what was happening? You had to put on your windshield wipers to get, literally, the oil slick off the window. That’s why I and so damn many other people I grew up with have cancer and why, for the longest time, Delaware had the highest cancer rate in the nation."
