In case you have forgotten

Sgt. Tyler Vargas-Andrews, a U.S. Marine Corps sniper, tells Congress that he was denied permission to shoot the suicide bomber in Afghanistan that killed 13 service members and over 170 civilians:

"Plain and simple, we were ignored. Our expertise was disregarded. No one was held accountable for our safety... The withdrawal was a catastrophe, in my opinion. There was an inexcusable lack of accountability."

Vargas-Andrews lost his right arm and left leg in the explosion.
