Special Counsel Robert Mueller's probe into possible Russian interference with the 2016 presidential election recently took a turn — lawyers for Army Lieutenant General Michael Flynn, the Trump Administration's former National Security Adviser, have stopped sharing information about the investigation with Trump’s legal team.

On Monday, Flynn's lawyers met with members of the special counsel team, raising speculation that Flynn might be cooperating with authorities and considering a plea bargain to testify against other members of the administration. 

Morning Edition’s Joe Mathieu spoke with WGBH News Legal Analyst and Northeastern Law Professor Daniel Medwed about the pros and cons of criminal cooperation agreements from the prosecution's standpoint.
