In 1985, President Ronald Reagan appointed me as a federal judge. I was 38 years old. At the time, I looked forward to serving for the rest of my life. However, I resigned Friday, relinquishing that lifetime appointment and giving up the opportunity for public service that I have loved. My reason is simple: I no longer can bear to be restrained by what judges can say publicly or do outside the courtroom. President Donald Trump is using the law for partisan purposes, targeting his adversaries while sparing his friends and donors from investigation, prosecution, and possible punishment. This is contrary to everything that I have stood for in my more than 50 years in the Department of Justice and on the bench. The White House’s assault on the rule of law is so deeply disturbing to me that I feel compelled to speak out. Silence, for me, is now intolerable.

With Levi as my model, in 1981 I became the deputy United States attorney and chief federal prosecutor of public corruption in Massachusetts. In about four years, my assistants and I won more than 40 consecutive corruption cases. Many convictions were of defendants close to the powerful mayor of Boston at the time. As a result, I received the Attorney General’s Distinguished Service Award and was appointed a federal judge. Some of the cases over which I presided as judge involved corruption and were highly publicized. Most notable was the prosecution of the notorious Boston mobsters James “Whitey” Bulger and Stephen “the Rifleman” Flemmi. Both, it turned out, were also FBI informants. Agents in the bureau, I discovered, were involved in crimes and egregious misconduct, including murders committed by Bulger and Flemmi. I wrote a 661-page decision detailing my findings. This led to orders that the government pay more than $100 million to the families of people murdered by informants whom the FBI had improperly protected. Their FBI handler was convicted twice and sentenced to serve a total of 50 years in prison.
