The reported altercation at Arlington National Cemetery involving Donald Trump’s staff was far from the first time that veterans or the families of service members have criticized the former president for words or behavior they saw as disparaging.

Since his first run for the White House, Trump has picked fights with the military and veterans that no other major U.S. politician would, dating back to 2015 when he dismissed the late Sen. John McCain’s military record because McCain had been a prisoner of war. Trump’s allies argue he supports service members while reserving the right to lash out against his critics.

“I think that if you want to know how Donald Trump values and honors those who’ve served, and particularly those who’ve given the ultimate sacrifice, I think you can just talk to these families and they have a much better read on this issue than anybody who has a grudge against Donald Trump,” said Ohio Sen. JD Vance, Trump’s running mate, on Monday.

Monday’s incident at Arlington National Cemetery took place as the former president visited the graves of some of the 13 U.S. service members killed in the Kabul bombing during the 2021 U.S. evacuation of Afghanistan. The Army says a cemetery official was “pushed aside” by Trump campaign aides while trying to prevent them from filming and photographing in Section 60, the burial site for military personnel killed while fighting in Afghanistan and Iraq.

The Trump campaign later posted footage of the visit on its social media accounts. The family of a decorated Green Beret whose grave appeared in the photos issued a statement supporting those who lost loved ones in Kabul but asking for understanding for the concerns from relatives of service members whose graves were near them.

Trump’s campaign did not respond to a request for comment for this story, but has contested the allegation that a campaign staffer pushed a cemetery official.

Jon Stoltz, a U.S. Army veteran and co-founder of veterans advocacy group VoteVets, which supports Vice President Kamala Harris’ candidacy, said Trump tried to use a sacred place “for a political ceremony.”

“They don’t have a right to do that with other veterans who are there,” Stoltz said.

The Arlington incident came less than two weeks after Trump came under criticism for the way he discussed the Congressional Medal of Honor, the military’s highest decoration for service members.

Praising billionaire Republican donor Miriam Adelson, whom he awarded the Presidential Medal of Freedom, the nation’s highest civilian award, Trump said she fared “much better” than receiving the Congressional Medal of Honor because recipients of that award are often badly injured or dead.

Despite the Veterans of Foreign Wars admonishing Trump by calling his comments “flippant” and “asinine,” he repeated a version of the remark at a campaign event in Michigan on Thursday, saying he’d “rather get” the Medal of Freedom because the Medal of Honor recipients, “oftentimes they’ve suffered greatly, right? They’ve suffered greatly or they’re not around.”
