GOP probe details deadly Afghanistan withdrawal, finds no direct role by Kamala Harris

House Republicans on Monday released the results of a sweeping three-year investigation they say is the most detailed public accounting yet of the Biden administration's chaotic withdrawal from Afghanistan that left behind hundreds of Americans and thousands of allies, some so desperate they clung to U.S. planes as the last military aircraft departed Kabul in 2021.

The report by House Foreign Affairs Committee Chairman Michael McCaul -- which relied on interviews with 18 top officials and 20,000 pages of documents -- blames the White House, its National Security Council and the State Department for being slow to listen to military generals who warned the security situation would deteriorate quickly once U.S. troops began to depart.

The investigation did not, however, find evidence that Vice President Kamala Harris played any role in the planning or execution of the evacuation, although she expressed public support for President Joe Biden's decision at the time.

Former President Donald Trump and other Republicans have suggested Harris is culpable, noting past comments by the vice president that she was the "last person in the room" when Biden decided to leave Afghanistan.

"Caused by Kamala Harris, Joe Biden, the humiliation in Afghanistan set off the collapse of American credibility and respect all around the world," Trump told National Guard members and their families in Detroit last month on the anniversary of the 2021 suicide bombing at Kabul's airport during the evacuation, which killed 13 U.S. service members and some 170 Afghans.

The Biden administration pushed back on the findings by Republicans, calling it a partisan effort that sought to cherry-pick facts ahead of an election.

The Republican probe also is being released ahead of the first political debate between Harris and Trump, which ABC News is hosting on Tuesday night in Philadelphia. Trump and GOP loyalists are expected to hammer the Democratic administration for failing to prepare for a Taliban takeover once U.S. troops began to depart.

"The chaos and devastation that took place in August of 2021 has forever damaged U.S. credibility in the eyes of our allies, while emboldening our adversaries like China, Russia and Iran," said McCaul, R-Texas. "Yet, not a single person was fired and, to this day, no one was ever held accountable by President Biden or Vice President Harris."

Last week, McCaul issued a subpoena for Secretary of State Antony Blinken's testimony on the withdrawal, threatening to hold him in contempt if he doesn't testify on Sept. 19. In a written statement, State Department spokesperson Matthew Miller noted that Blinken has already testified on Afghanistan and the State Department provided the 20,000 pages of documents the committee was relying on to inform its investigation.

"Though the secretary is currently unavailable to testify on dates proposed by the committee, the State Department has proposed reasonable alternatives to comply with Chairman McCaul's request for a public hearing," Miller said. "It is disappointing that instead of continuing to engage with the Department in good faith, the committee instead has issued yet another unnecessary subpoena."

On the investigation, Miller accused Republicans of politicizing the war and "presenting inaccurate narratives."

"The State Department remains immensely proud of its workforce who put themselves forward in the waning days of our presence in Afghanistan to evacuate both Americans and the brave Afghans who stood by our sides for more than two decades," he said.

While many of the details included in the Republican investigation have already become public through media reports and internal government reviews, among the more interesting details come from inside-the-room accounts of U.S. Embassy personnel.

At one point, according to Republicans, staff grew so panicked at the rushed evacuation that they began filling Tupperware containers with passports and visa foils to burn as Taliban forces arrived outside their building. Classified documents were eventually left behind in the scramble, according to the report, although the report doesn't say how many or what type.

Meanwhile, the NSC was slow to establish criteria for who was eligible for evacuation, a standard the report says changed hourly. At one point, electronic visa letters known as "hall passes" were given to eligible Afghans, but the documents were so easily replicated that bootleg copies began circulating and the U.S. quickly scrapped the plan, according to the report.

The report also paints a picture of a State Department and NSC slow to understand the danger U.S. personnel were in as the Afghanistan government collapsed and the Taliban took control.

Ambassador Ross Wilson, who was brought out of retirement in the Trump administration to serve in Afghanistan and was the top American diplomat in Kabul at the time of the withdrawal, was allegedly reluctant to trigger a military-led evacuation, according to the report. Wilson has spoken publicly before that his staff worked feverishly in those final days to try to process as many travel documents as possible to help qualified people evacuate.

Biden has defended the State Department's handling of the evacuation in the wake of the operation.

"In the 17 days that we operated in Kabul after the Taliban seized power, we engaged in an around-the-clock effort to provide every American the opportunity to leave. Our State Department was working 24/7 contacting and talking, and in some cases, walking Americans into the airport," Biden said in 2021 in the wake of the withdrawal.

Biden and other Democrats have also defended the decision to pull out U.S. troops and shutter the embassy after 20 years in the country, saying their options were limited after Trump struck a deal with the Taliban to depart by May 1, 2021.

Trump's agreement with the Taliban included the departure of U.S. troops and the release of 5,000 Taliban fighters from Afghan prisons so long as the Taliban promised not to collaborate with al-Qaeda or engage in "high-profile" attacks.

Wanting to bring an end to the war and concerned that Taliban fighters might target American service members if the U.S. reneged on the deal, the Biden administration stayed the course but amended the U.S. withdrawal deadline to Aug. 31, 2021.

"He could either ramp up the war against a Taliban that was at its strongest position in 20 years and put even more American troops at risk or finally end our longest war after two decades and $2 trillion spent," said Sharon Yang, the White House spokesperson for oversight and investigations. "The President refused to send another generation of Americans to fight a war that should have ended long ago."

Military generals in charge at the time have previously testified that their recommendation to Biden earlier that year was to maintain some 2,500 troops beyond that date regardless of what Trump had agreed to.

"At the end of 20 years, we the military helped build an army, a state, but we could not forge a nation. The enemy occupied Kabul, the overthrow of the government occurred and the military we supported for two decades faded away," Gen. Mark Milley, who served as chairman of the Joint Chiefs of Staff at the time of the withdrawal, testified last March.

"That is a strategic failure," he said.
