Federal prosecutors on Friday revealed the full transcript of the voicemail a personal attorney for President Donald Trump left with Michael Flynn’s lawyer after the former national security adviser withdrew from a joint defense agreement, a signal that he had agreed to cooperate with the special counsel’s investigation.

Much of the transcript of the Nov. 22, 2017, voicemail left with Covington & Burling’s Robert Kelner had previously been disclosed in the 448-page report prepared by Special Counsel Robert Mueller III and his team.
