Special Counsel Robert Mueller spoke publicly for the first time about his investigation into President Donald Trump on Wednesday, drawing a clear contrast between the contents of his 448-page report and the summary provided two months ago by Attorney General William Barr. In particular, Mueller emphasized that his team’s findings did not exonerate Trump on the question of obstruction, and clarified that he did not indict Trump because he thought it was unconstitutional to do so for a sitting president. Some have also interpreted Mueller’s remarks as a hint that it was now time for Congress to take up impeachment proceedings.

To decipher what this all means, Jim Braude was joined by Don Stern, who worked alongside Mueller at the Department of Justice and in private practice at Hale and Dorr, and Bruce Singal, who worked alongside Mueller in the U.S. Attorney’s office in Boston.
