President Trump has told advisers that he wants to withdraw all U.S. troops from Afghanistan by the 2020 election, NBC News reported.
Officials at the Defense and State departments disagree over whether a withdrawal should be done and the timing of it.
Last December, Trump threatened to pull troops out of Afghanistan and to close the U.S. Embassy in Kabul. The president reportedly argued that without the military, embassy personnel might not be safe.
Military officials have pushed back against the plan to pull out all troops within the next 15 months, officials told NBC. Miller would consider withdrawing some troops but would want others to remain to fight ISIS or al Qaeda. Trump has called for ending the war in Afghanistan, including during his 2016 campaign.
