Ex-US NSA helped in Russia probe, shouldn't go to jail: Mueller
Special Counsel Robert Mueller, who's investigating alleged Russian collusion in the 2016 US presidential elections, has recommended that ex-National Security Adviser Michael Flynn shouldn't serve prison time as he provided "substantial assistance" to the investigation. Flynn had pleaded guilty to lying to the FBI about his interactions with Russia's ambassador to the US, Sergey Kislyak, in 2016.
