Actually Obama started the process.

President Barack Obama had promised to end the war, so on Dec. 28, 2014, U.S. and NATO officials held a ceremony at their headquarters in Kabul to mark the occasion.

In a statement, Obama called the day “a milestone for our country” and said the United States was safer and more secure after 13 years of war.
“Thanks to the extraordinary sacrifices of our men and women in uniform, our combat mission in Afghanistan is ending and the longest war in American history is coming to a responsible conclusion,” he declared.

Obama had scaled back military operations over the previous three years, but he failed to pull the United States out of the quagmire. At the time of the ceremony, about 10,800 U.S. troops remained, a decrease of almost 90 percent from the surge of forces that he had sent to Afghanistan in his first term. Obama promised to withdraw the rest of the troops by the end of 2016, coinciding with the end of his term in office, save for a residual force at the U.S. Embassy.

Trump maintained the presence. Why didn't Obama fulfil his promise to withdraw all troops?
