Sanders: I Support Obama’s Decision to Leave Troops in Afghanistan

STEPHANOPOULOS: "Also, big questions about national security. President Obama announcing this week that he would keep almost 10,000 troops in Afghanistan through next year, more than 5,000 after that. You just heard Ben Carson say he supports that decision, so does Hillary Clinton. Do you?"
SANDERS: "Well, yeah, I won’t give you the exact number. Clearly, we do not want to see the Taliban gain more power and I think we need a certain nucleus of American troops present in Afghanistan to try to provide the training and support the afghan Army needs."
