Trump's presence at the hallowed Arlington National Cemetery -- intended to provide a campaign boost ahead of the November 5 vote -- has instead mushroomed into a public dispute consuming the candidates and the military.

"Let me be clear: the former president disrespected sacred ground, all for the sake of a political stunt," Harris said of Monday's incident at the cemetery near Washington, where Trump defied the rules and posed for photos with relatives of US service members killed in Afghanistan.

In one image, he is standing with family members of a fallen Marine, posing among headstones while grinning broadly and giving a thumbs-up.

"If there is one thing on which we as Americans can all agree, it is that our veterans, military families, and service members should be honored, never disparaged, and treated with nothing less than our highest respect and gratitude," Harris wrote on X.

- 'Abruptly pushed aside' -

On Thursday, the US Army issued a rare statement confirming that a cemetery staff member had been "abruptly pushed aside" after asking Trump's team to stop filming in a burial section for those killed in recent wars, where photography for political purposes is banned.

Trump's campaign team has gone on the offensive by describing the employee as a "despicable individual" and claiming she was suffering a mental health episode.

But the military said the staff member had "acted with professionalism" and it condemned the incident as "unfortunate."

Trump has made criticism of the Biden-Harris administration's handling of the US retreat from Afghanistan a keynote of his campaign, arguing that he would have managed it better.

He visited the cemetery with families of some of the 13 service members killed in a 2021 bombing in Kabul during the last, chaotic hours of the US withdrawal.

Trump's relationship with the military has long spawned controversy.

While often touting his support for the armed forces, he privately mocked the war dead while he was president and did not want to be seen near military amputees, according to his former chief of staff.

Harris's blunt response Saturday over the cemetery incident appeared to underline her determination to take the fight directly to Trump in what is shaping up to be a bruising presidential election.

Trump has repeatedly mocked Harris's name, intelligence, appearance and racial identity, while the Harris campaign has replied that the former president is "weird," an aspiring dictator, and "out of his mind."

Harris earlier faced withering criticism over the cemetery incident from Trump's running mate, Senator J.D. Vance, who has launched a series of fierce attacks against the vice president.

Apparently responding to a mistaken report that Harris had already reacted to the cemetery visit, Vance accused her of feigning outrage and said, "She can go to hell."

"Don't focus on Donald Trump showing up to grieve with some people who lost their children. Focus on your own job. Don't do this fake outrage thing," he later told the Washington Post.

At that point Harris had not publicly mentioned the cemetery visit.
