The leak of a July State Department cable warning senior officials of Kabul’s potential for a swift collapse has increased lawmakers’ concerns about the Biden administration’s grasp of the situation in Afghanistan.

On Thursday, the Wall Street Journal reported that 23 staffers stationed at the U.S. Embassy in Kabul sent a cable on July 13 via the State Department’s dissent channel warning of the Taliban’s rapid advance and potential collapse of the Afghan security forces and calling for evacuation efforts to be increased.
