Donald Trump suffered more blows to his presidential campaign Friday when a CIA ex-director accused him of being an "unwitting agent" of Russia, as polls showed rival Hillary Clinton surging, even in traditional Republican strongholds. Trump's drive for the White House hit another snag when he made the rare acknowledgement of an error, backtracking from claims that he saw video footage of money being transferred to Iran by secret plane. The latest setback came in the form of harsh criticism by Michael Morell, a 33-year veteran of the Central Intelligence Agency who served presidents of both parties and then helmed the agency in 2011.
