WASHINGTON (AP) — A defense official says Donald Trump’s campaign was warned about not taking photographs before an altercation at Arlington National Cemetery during a wreath-laying ceremony earlier this week to honor service members killed in the Afghanistan War withdrawal. The official spoke on condition of anonymity to discuss a sensitive matter concerning Monday’s events. It came a day after NPR reported that two Trump campaign staff members “verbally abused and pushed” aside a cemetery official who tried to stop them from filming and photographing in Section 60, the burial site for military personnel killed while fighting in Afghanistan and Iraq. Trump’s campaign contends he was granted access to a photographer and disputes a physical altercation.
