WASHINGTON (Reuters) -Republican presidential candidate Donald Trump used the third anniversary on Aug.21 of the U.S. withdrawal from Afghanistan to try to pin the chaotic pullout on his Democratic rival for the White House, Kamala Harris. 

Trump participated in a wreath-laying ceremony at Arlington National Cemetery honoring the 13 servicemembers killed during the U.S. exit, then later in Detroit blamed Harris, the vice president, and President Joe Biden for what he termed a "catastrophic" withdrawal.

"Caused by Kamala Harris, Joe Biden, the humiliation in Afghanistan set off the collapse of American credibility and respect all over the world," Trump said in an address to the National Guard Association of the United States.

It was the latest attempt by Trump and his campaign to raise doubts about Harris' fitness to serve as commander-in-chief as the Nov. 5 election draws near and comes after Harris last week proclaimed herself ready to lead the nation's armed forces.

The U.S. troop pullout and evacuation of U.S. and allied officials, citizens and Afghans at risk of Taliban retribution saw crowds of desperate Afghans trying to enter Kabul airport and men clinging to aircraft as they taxied down runways in August 2021.

An Islamic State suicide bomber killed 13 U.S. servicemembers and more than 150 Afghans outside an airport gate.

Harris' campaign said the fault lay with Trump's tenure as president.

"The Biden-Harris administration inherited a mess from Donald Trump," said Ammar Moussa, a Harris spokesperson. "Trump wants America to forget that he had four years to get out of Afghanistan, but failed to do it."

A review released by the U.S. State Department in 2023 found fault with both the Trump and Biden administrations in the run-up to the withdrawal. 

In recent weeks, Trump and his running mate, Senator JD Vance, also have sought to turn Democratic vice presidential candidate Tim Walz's decades of service into a political vulnerability. Former military service is often a key selling point for candidates in U.S. political campaigns.

The Republicans have accused Walz of exaggerating his rank in the Army National Guard, where he served for 24 years. Walz has described himself as a retired command sergeant major, one of the highest noncommissioned officer positions in the Army. While he achieved that rank, he did not meet the requirements to retire with that title. 

The Harris campaign deleted a reference this month to Walz's rank as a "command sergeant major" on its website. The campaign also now says Walz "misspoke" in 2018 during his gubernatorial campaign in Minnesota when he referred to "weapons of war, that I carried in war." Walz was never deployed to a war zone.

Trump, 78, never served in the military. Though he was of draft age during the Vietnam War, he received four student deferments and a health-related one after he received a diagnosis for bone spurs in his feet. 

Vance served in the Marine Corps for four years as a combat correspondent and was deployed to Iraq for roughly seven months. His position mainly involved writing reports of military activity for public dissemination and at times interacting with the media.   

The Harris campaign has zeroed in on remarks Trump made this month at a press conference in which he stated the Presidential Medal of Freedom, a civilian award, is superior to the Medal of Honor, which is given to the military by Congress.

“Everyone (who) gets the congressional Medal of Honor, they’re soldiers," Trump said. "They’re either in very bad shape because they’ve been hit so many times by bullets or they’re dead.”

A spokesperson for Harris said the remarks by Trump, who has a history of statements casting doubt on the valor of soldiers killed, wounded or captured in action, were an “insult” to the recipients of the award. 

Harris told CNN in 2021 that she was the last person in the room with Biden when he decided to pull U.S. forces from Afghanistan and end America's longest war. She also said that she was comfortable with Biden's decision, but it remains unclear what role she played in the discussion.

Both Biden and Harris released statements marking the anniversary on Monday.

"These 13 devoted patriots represent the best of America, putting our beloved nation and their fellow Americans above themselves and deploying into danger to keep their fellow citizens safe," Harris said.

During her acceptance speech at the Democratic National Convention last week, Harris said she was ready to assume the role of commander-in-chief.

“I will ensure America always has the strongest, most lethal fighting force in the world,” Harris said.
