US Gen. McKenzie says Taliban were 'helpful and useful' in final hours of evacuation

McKenzie said the Taliban were 'helpful and useful when we closed down operations'

McKenzie's comments come as the news broke Monday that the last U.S. forces in Afghanistan had departed the country, officially bringing the 20-year conflict to an end. The removal of U.S. forces met the Aug. 31 timeline that the Biden administration had agreed to with the Taliban, though the White House did acknowledge Monday that a "small number" of Americans were not able to make it out of the country.
