A clip of President Biden on Wednesday appearing to claim in a speech that he has cancer sparked alarm on Twitter.

Biden was visiting a former coal power plant in Somerset, Massachusetts, to discuss new executive orders to fight climate change.

While discussing the harm caused by emissions from oil refineries, Biden referenced his childhood home in Delaware and said that he and many other people he grew up with now "have" cancer.

"My mother drove us rather than us being able to walk and guess what? The first frost, you know 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," Biden said.
