The State Department, in a memo dated September 14, demanded that the Taliban surrender all known al-Qaeda associates in Afghanistan, provide intelligence on bin Laden and his affiliates, and expel all terrorists from Afghanistan. On September 18, the director of Pakistan's Inter-Services Intelligence, Mahmud Ahmed conveyed these demands to Mullah Omar and the senior Taliban leadership, whose response was "not negative on all points". Mahmud reported that the Taliban leadership was in "deep introspection" and waiting for the recommendation of a grand council of religious clerics that was assembling to decide the matter. On September 20, President Bush, in an address to Congress, demanded the Taliban deliver bin Laden and other suspected terrorists and destroy the al-Qaeda bases. "These demands are not open to negotiation or discussion. The Taliban must act and act immediately. They will hand over the terrorists, or they will share in their fate."
