The chief U.S. envoy to the Taliban, U.S. Ambassador Zalmay Khalilzad, tendered his resignation Monday in a letter sent to Secretary of State Antony Blinken. His departure from the job of special representative for Afghanistan Reconciliation goes into effect on Tuesday. He told Blinken that it was "the right time" to leave, "at a juncture when we are entering a new phase in our Afghanistan policy."
CBS News viewed a copy of the letter in which Khalilzad laid out the work he did in brokering a "conditions-based agreement" between the Taliban and the U.S. to end American military engagement in Afghanistan but also acknowledges that the part of the agreement involving the Taliban and Afghan government "did not go forward as envisaged."
