From CBS News:
Now-fired former FBI deputy director Andrew McCabe oversaw a federal criminal investigation into whether Attorney General Jeff Sessions lacked candor when testifying before Congress last year about his contacts with Russian officials, a source familiar with the investigation tells CBS News’ Paula Reid. Sessions fired McCabe late Friday, at the recommendation of FBI officials.
The investigation was opened before special counsel Robert Mueller was appointed, Reid reports. A Justice Department official says Sessions was not aware of this investigation until he found out about it from reports.
ABC News first reported that McCabe had been in charge of the investigation into Sessions. Sessions’ testimony raised alarm bells, but this is the first time it has been reported that there was actually a criminal probe of Sessions’ actions.
