The special counsel investigating alleged Russian collusion in the 2016 US election will not be pursuing a jail sentence for former national security adviser Michael Flynn.
Mr Flynn has admitted lying to the FBI.
But in a memo, Robert Mueller said Mr Flynn had provided “substantial” details about links between the Trump election team and Russian officials.
The heavily redacted memo hints at future revelations in a criminal probe that could trouble Donald Trump.
President Trump has called the investigation a witch hunt and denies there was any collusion between his team and Russian officials to try to secure his election victory.
