Afghanistan Papers

The Afghanistan Papers are a set of internal documents from the Special Inspector General for Afghanistan Reconstruction (SIGAR) obtained by "The Washington Post" through a Freedom of Information Act request that document the US war in Afghanistan. The documents reveal that high-ranking officials were generally of the opinion that the war was unwinnable, but kept this hidden from the public. Due to the difficulty of creating metrics to objectively demonstrate success, they had been manipulated for the duration of the conflict. NPR host Lulu Garcia-Navarro said that the "new Pentagon Papers describe explicit and sustained efforts by the US government to deliberately mislead the public.”
Initial reporting in "The Washington Post".
The initial article derived from these papers, titled "At War With the Truth," was published by "The Washington Post" reporter Craig Whitlock on December 9, 2019. Shortly thereafter, numerous publications built on Whitlock's writing.
The report, titled “Lessons Learned,” estimates that 40% of U.S. aid to Afghanistan since 2001 ended up in the pockets of corrupt officials, warlords, criminals and insurgents. Ryan Crocker, former ambassador to Afghanistan and Iraq, told the investigators in a 2016 interview, "You just cannot put those amounts of money into a very fragile state and society, and not have it fuel corruption." 
Reactions of public officials.
Due to the nature of the content within the Afghanistan Papers, numerous public officials commented on their content in the days following Whitlock's initial article. The following is a sampling of select politicians:
Senator Rand Paul: "I think our young men and women that we send to war, our best and our brightest, they deserve better. They deserve an open airing of what is the mission. I've been saying for several years now that I can't meet a general anywhere who can tell me really what is the mission we're trying to accomplish in Afghanistan."
Senator Kirsten Gillibrand: "We all read today, the striking reporting by The Washington Post, suggesting that administration officials, potentially including military officials, have misled the American public about the war in Afghanistan. I am writing to request hearings to address these deeply concerning revelations about the Afghan war.”
Representative Tulsi Gabbard said she introduces legislation for a Congressional inquiry into "the lying and wasting of taxpayer dollars" and lives of US service members. She accused the military-industrial complex, contractors and consultancy companies of profiting from "a scam that ripped the US taxpayers off over a trillion dollars since 9/11 in Afghanistan alone." Gabbard reiterated her request to bring US troops home from Afghanistan.
Former Vice President Joe Biden distanced himself from Barack Obama's Afghan war policy, saying: "I’m the guy from the beginning who argued that it was a big, big mistake to surge forces to Afghanistan."
