An Army investigative report obtained by The Washington Post details how senior officials from the White House and State Department failed to comprehend how quickly the Taliban was taking over Afghanistan. The report also detailed how American troops on the ground in Afghanistan faced increased danger as a result of decision-making from top brass.

The 2,000-page report was obtained by The Post through a Freedom of Information Act (FOIA), according to the newspaper. It’s the latest insight into just how unprepared President Joe Biden’s administration appeared to be with regards to the Afghanistan withdrawal.

The Army investigation came about after the Aug. 26 suicide bombing outside of the Kabul airport. It includes previously unreported acts of violence against American personnel in Afghanistan, complaints from commanders on the ground and more.
