Sen. Lindsey Graham (R-SC), a strong support of the Afghan war, chimed in Sunday on the news that a U.S. service member in the region opened fire and killed up to 16 Afghan civilians.
"I believe, one, this is tragic and will be investigated, and that soldier will be held accountable for his actions under the military justice system," Graham said on ABC's This Week. "Unfortunately, these things happen in war. You had an Israeli soldier kill worshippers by the Dome of the Rock mosque. You just have to push through these things."
