Former President Donald Trump’s campaign stirred new controversy this week during a visit to Arlington National Cemetery that was intended to draw attention to the chaotic US withdrawal from Afghanistan in 2021.

An individual physically blocked Trump’s team from accompanying him during the Monday visit, two Trump campaign officials said. A cemetery spokesperson confirmed to CNN “there was an incident” and a “report was filed” but didn’t provide further details.

Trump was visiting the cemetery following a wreath laying to honor 13 US military service members who were killed at Kabul airport’s Abbey Gate. Monday marked three years since the tragedy.

In a post on Truth Social, Trump appeared to suggest the incident stemmed from his campaign’s use of photography, sharing a statement from the family members of the fallen soldiers expressing their approval.

“We had given our approval for President Trump’s official videographer and photographer to attend the event, ensuring these sacred moments of remembrance were respectfully captured and so we can cherish these memories forever,” the families said.

But according to a statement from Arlington National Cemetery obtained by CNN, federal law prohibits political campaign or election-related activities within Army National Military Cemeteries.

The cemetery said it “reinforced and widely shared this law and its prohibitions with all participants” which includes “photographers, content creators or any other persons attending for purposes, or in direct support of a partisan political candidate’s campaign.”

Trump’s post came after a report from NPR about a “verbal and physical altercation.” A source with knowledge of the incident told the outlet that a cemetery official attempted to prevent Trump’s team from photographing and filming in the area where recent US casualties are buried. In response, Trump campaign staff “verbally abused and pushed the official aside,” according to NPR.

Trump spokesperson Steven Cheung disputed claims of a physical altercation, but said an unnamed individual decided to “physically block members of President Trump’s team during a very solemn ceremony.”

Cheung suggested Trump’s team has video to back up the claim.

Trump campaign manager Chris LaCivita shared a similar account with CNN. “President Trump was there on the invitation of the Abbey Gate Gold Star Families to honor their loved ones who gave the ultimate sacrifice for their country,” LaCivita said.

“For a despicable individual to physically prevent President Trump’s team from accompanying him to this solemn event is a disgrace and does not deserve to represent the hallowed grounds of Arlington National Cemetery,” LaCivita continued.
