A retired FBI agent has pleaded not guilty to charges of lying under oath during the 2013 mob trial of James "Whitey" Bulger.

Robert Fitzpatrick, 75, faces six federal counts of perjury and six counts of obstruction of justice, reports He is accused of falsely portraying himself as a whistleblower who tried to end the FBI’s involvement with Bulger, a former organized crime figure, when the latter was an informant to the bureau between 1975 and 1990.

The indictment, filed on Tuesday, says Fitzpatrick made “false material declarations designed to aid Bulger’s defense” during his testimony under oath in July 2013 and falsely testified about his accomplishments as a former FBI supervisor.

Fitzpatrick has claimed for years – including in his 2011 book, Betrayal, Whitey Bulger and the FBI Agent Who Fought To Bring Him Down – that he fought to bring Bulger down. This indictment discredits those assertions.

Fitzpatrick’s attorney said Thursday that his client “adamantly maintains his innocence and looks forward to challenging the government’s accusations as soon as possible.”

Bulger, 85, was sentenced to life in prison in a case that exposed deep corruption within the FBI.
