Joe Biden appeared to make the bizarre claim that he has ' cancer ' while delivering a speech on climate change on Wednesday.
Mr Biden was speaking at the site of a former coal-fired power plant in Somerset, Massachusetts when he appeared to say he "has" cancer.
Mr Biden talked about growing up in Claymont, Delaware, which has many oil refineries.
He said: "You'd have to put on your windshield wipers to get literally the oil slick off the window."
He added: "That's why I — and so damn many other people I grew up with — have cancer."
The White House press office has not publicly clarified Wednesday's statement but Mr Biden has previously had non-melanoma skin cancers removed before becoming President.
A White House health report states: "It is well-established that President Biden did spend a good deal of time in the sun in his youth.
"He has had several localized, non-melanoma skin cancers removed with Mohs surgery before he started his presidency. These lesions were completely excised, with clear margins."
It added: "Total body skin exam was performed for dermatologic surveillance. Several small areas of actinic change were treated with liquid nitrogen cryotherapy, but there are no areas suspicious for skin cancer at this time. No biopsies were required."
When Mr Biden underwent his physical in November 2021, Dr Kevin O'Connor wrote he is still monitored for lesions.
He wrote: "It is well-established that President Biden did spend a good deal of time in the sun in his youth.
"He has had several localized, non-melanoma skin cancers removed with Mohs surgery before he started his presidency. These lesions were completely excised, with clear margins.
"Total body skin exam was performed for dermatologic surveillance.
"Several small areas of actinic change were treated with liquid nitrogen cryotherapy, but there are no areas suspicious for skin cancer at this time. No biopsies were required."
In Mr Biden's speech on Wednesday, he blamed Republicans for stalling his green agenda.
He said: "Not a single Republican in Congress stepped up to support my climate plan, not one."
He added: "Let me be clear, climate change is an emergency.
"And, in the coming weeks, I'm going to use the power I have as president to turn these words into formal official government actions through the appropriate proclamations, executive orders and regulatory powers that a president possesses."
