The family of a Green Beret who died by suicide after serving eight combat tours and is buried at Arlington National Cemetery expressed concern on Wednesday that Donald J. Trump’s campaign had filmed his gravesite without permission as Mr. Trump stood in an area where campaign photography isn’t allowed.

Relatives of Master Sgt. Andrew Marckesano issued their statement two days after Mr. Trump’s visit, which also included a confrontation between members of the Trump campaign and an Arlington employee. The former president’s campaign took video in a heavily restricted section of the cemetery known as Section 60, which is largely reserved for the fallen veterans of the Iraq and Afghanistan wars.

A woman who works at the cemetery filed an incident report with the military authorities over the altercation. But the official, who has not been identified, later declined to press charges. Military officials said she feared Mr. Trump’s supporters pursuing retaliation.

Sergeant Marckesano died on July 7, 2020, after moving to Washington to begin a job at the Pentagon. He had three children, and friends said he had chronic post-traumatic stress disorder from his time in combat. He earned Silver and Bronze Stars during his service. His gravesite is adjacent to that of Staff Sergeant Darin Taylor Hoover, a Marine who was killed in the 2021 bombing at Abbey Gate outside the Kabul airport in Afghanistan.

The Hoover family granted permission to the Trump team to film and take photographs at the gravesite; the Marckesano family did not, and filming and photographing at the gravesite for political purposes is a violation of federal law, according to cemetery officials. Yet Sergeant Marckesano’s grave was shown in photos from the visit that were published online. A video was posted to Mr. Trump’s TikTok account featuring footage from the Section 60 visit and the gravestones from behind, with narration criticizing the handling of the U.S. withdrawal from Afghanistan in 2021.

In a statement from Sergeant Marckesano’s relatives after being contacted by The New York Times, his sister, Michele, said, “We fully support Staff Sergeant Darin Hoover’s family and the other families in their quest for answers and accountability regarding the Afghanistan withdrawal and the tragedy at Abbey Gate.”
