Nearly a year before Attorney General Jeff Sessions fired senior FBI official Andrew McCabe for what Sessions called a "lack of candor," McCabe oversaw a probe into whether Sessions himself lacked candor when testifying before Congress about contacts with Russian operatives, ABC News reported Wednesday. One source told ABC Sessions was not aware of the investigation when he decided to fire McCabe last Friday. McCabe's firing came less than 48 hours before McCabe was to retire from government and obtain a full pension.
