@dawgitsbananas: Beau Biden died of glioblastoma, a highly aggressive form of brain cancer, on May 30, 2015, at the age of 46. He passed away at Walter Reed National Military Medical Center in Bethesda, Maryland. President Joe Biden has suggested a potential link between his son's cancer and exposure to toxic burn pits during his military service in Iraq. #joebiden #usa #History #emotional #usmilitary
