A former top CIA official emphatically endorsed Hillary Clinton for president on August 5, 2016, calling Donald Trump an "unwitting agent" of Russian President Vladimir Putin."Mr. Putin played upon Mr. Trump's vulnerabilities by complimenting him," wrote former CIA deputy director Michael Morell in a New York Times op-ed. "In the intelligence business, we would say that Mr. Putin had recruited Mr. Trump as an unwitting agent of the Russian Federation." / AFP PHOTO / MANDEL NGAN
