The VA refuses to recognize any link between burn pits it used in Iraq and Afghanistan, and serious health problems for people exposed to them. This creates problems with getting medical attention and benefits for thousands of men and women.
But now former Vice President Joe Biden is saying his son Beau might have died of brain cancer as a direct result of the burn pits.
A book - 'The Burn Pits' by Joseph Hickman, features an entire chapter on Beau Biden.
'[T]hat stunned me. I didn't know that,' Biden said in an interview with PBS News Hour on Wednesday.
