HOWIE CARR: Come clean on FBI frame-up, Bob Mueller. “What did Bob Mueller know about the FBI’s framing of four innocent men for a murder they didn’t commit, and when did he know it? This is an important question for the ‘special counsel,’ and for two days I’ve been emailing his press office, asking for answers about his tenure in the U.S. attorney’s office here. No response. Zip, zero, nada.”

Plus: “In 2013, the Boston Globe also reported the existence of a Mueller letter. The Parole Board now cannot find it. I found other two U.S. attorneys’ letters in the state archives — but none from Mueller. The special counsel’s office is not commenting. So let me ask the question again: Mr. Mueller, what did you know about the framing of four innocent men for a crime they did not commit? Did you ever write any letters demanding that the parole board not correct this gross miscarriage of justice? When did you find out that the FBI office in Boston was in the business of framing innocent men on behalf of their serial-­killing, cocaine-dealing underworld paymasters? And what exactly did you do about it when you ran that agency for eight years?”
