WASHINGTON (Reuters) - A former spy for the U.S. Central Intelligence Agency was sentenced on Friday to 20 years in prison after being convicted on charges of conspiring to transmit U.S. defense secrets to China, the Justice Department said. Kevin Patrick Mallory, of Leesburg, Virginia, was found guilty by a federal jury in June 2018 of several counts of conspiring to provide national defense information to aid a foreign government and making false statements.
