Did Joe Biden say he has cancer in his climate speech at a Massachusetts power plant?

President Joe Biden sparked speculation about his health Wednesday during a speech in Massachusetts where he said, "That's why I, and so damn many other people I grew up with, have cancer, and why can- -- for the longest time, Delaware had the highest cancer rate in the nation."

Joe Biden was in Somerset, Massachusetts visiting the former coal-fired Brayton Point power plant, to announce new actions on climate change.

Biden did not declare a national climate emergency, but said that the climate crisis is an emergency "and I will look at it that way."

Twitter reaction

Some people took to Twitter wondering if it was just a misspeak or if he actually announced he has cancer.

RNC research asked "Did Joe Biden just announce he has cancer?" with a quote from Biden's speech.

Glenn Kessler, a Washington Post journalist quote-tweeted the RNC Research tweet to say "How dumb is this tweet? Check out Biden's medical report. Before he became president, he'd had non-melanoma skin cancers removed. Has no one at @RNCResearch ever had this common procedure?"

Kessler is an editor and writer of The Fact Checker, according to the Washington Post website.

About two-thirds of the way through his speech in Somerset, Biden was telling a story about growing up in Claymont, Delaware. He was relating his memories of his mother wiping oil slicks off their car, to McCarthy's stories of people in Somerset taking rags to wipe the coal dust off their cars.

Biden was advocating for clean energy and the removal of toxins and debris from the environment when he said: "That's why I, and so damn many other people I grew up with, have cancer."
