Michael Flynn assisted in Mueller's obstruction and WikiLeaks investigations

As part of his guilty plea, President Trump's former national security adviser Michael Flynn assisted special counsel Robert Mueller in his investigations into the Trump campaign's discussions of WikiLeaks, as well as "potential efforts to interfere or otherwise obstruct" the special counsel, according to a new court filing.

Details: The filing, which states that Flynn is ready for sentencing, claims that the former top Trump aide informed prosecutors of multiple instances in which "either he or his lawyers received communications from persons connected to the Administration or Congress that could have affected both his willingness to cooperate and the completeness of that cooperation." The filing also states that Flynn "provided a voicemail recording of one such communication."
