Attorney General Edwin Meese III has fired the Justice Department's chief spokesman, Terry Eastland, saying he has done an inadequate job of defending the attorney general in a year-old criminal investigation, Eastland said Monday. "Today's my last today; I don't have a job," Eastland told a reporter. In a letter to Meese, Eastland noted that he had been relieved of his duties Friday. He wrote to Meese, "You have expressed to me your desire to have as director of public affairs someone who is willing to aggressively defend you against, in effect, any and all criticism." Eastland said that he had defended Meese "to the best of my ability," while "excercising good judgment and acting in a manner consistent with the obligations of this office."
