 Biden once or a couple of times said his son Beau died in Iraq. No, he didn't. Then Biden suggested that his son contracted brain cancer in Iraq because he was near a burn pit. But studies show that the percentage of soldiers serving in Iraq who contracted cancer is no higher than those who served in other wars. No evidence whatsoever. There's a direct link between Beau's brain cancer and the fact that he served in Iraq and lived near a burn pit.
