On Sept. 7, 2019, about one year before the Taliban prisoners were all freed, Trump himself tweeted a small thread about the plans, saying that the Taliban leaders were going to "secretly meet" with him at Camp David on Sept. 8, just three days before the anniversary of the Sept. 11 attacks. This raised eyebrows, as the Taliban had previously "forged a close relationship" with al-Qaida, the terrorist group that carried out the attacks, according to Brittanica.com.
