The office investigating Russian collusion in the US election has recommended that ex-national security adviser Michael Flynn should not have to serve a jail sentence.
Special Counsel Robert Mueller’s office said Mr Flynn had provided “substantial assistance” in its investigation.
Mr Flynn has admitted one count of lying to the FBI.
He is the only member of the Trump administration so far to plead guilty as a result of the investigation.
President Donald 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.
The decision to recommend no jail time comes in a memo to be sent to the judge overseeing Mr Flynn’s sentencing.
He will be sentenced in the US District Court for the District of Columbia on 18 December.
Mr Flynn’s short tenure as Mr Trump’s national security adviser ended in February 2017 after just 23 days.
He was forced out over revelations that he had discussed lifting US sanctions on Russia with the Russian ambassador to Washington before Mr Trump took office, and that he lied to the US vice-president about that conversation.
Mr Flynn had been a fervent supporter of Mr Trump during the election campaign.
