Former U.S. attorney Preet Bharara said Friday that aiding Robert Mueller's special counsel investigation may be the only "sane" move remaining for former national security adviser Mike Flynn.
Flynn has become a central part of the ongoing federal investigation into possible collusion between the Trump campaign and Russia.
In a tweet Friday morning, the former U.S. attorney who was fired by President Trump said that aiding Mueller might be Flynn's only chance to save himself and his son after recent reports that prosecutors have enough evidence to charge Flynn and his son, Michael Flynn Jr., who also worked on the campaign.
"If you're dead to rights, flipping on others and cooperating with the prosecution is the only sane and rational move," Bharara tweeted.
"Also, prosecutors accept cooperation only if you can provide 'substantial assistance,'" he tweeted, adding that he believes that means Flynn could provide evidence on his superiors.

Bharara's tweet comes a day after it was reported that Flynn's lawyers have terminated an information-sharing agreement with lawyers representing Trump and other White House officials, a sign that Flynn may be moving to cooperate with the investigation.
Trump's legal team has suggested the probe will wind down in the coming weeks, but legal experts say this is unlikely.
Flynn's lawyers notified the White House legal team of the end of the agreement in the past few days. In October, the special counsel investigation entered a new phase when indictments were handed down against former Trump campaign chair Paul Manafort and his associate Robert Gates.
Gates and Manafort have plead not guilty to the charges, which include fraud and money laundering.
