    October 5, 2007


    In a private ceremony this afternoon, Thomas P. O’Brien was sworn in as the United States Attorney for the Central District of California.

    O’Brien was sworn in by United States District Judge John F. Walter in his courtroom in the United States Courthouse in Los Angeles.

    O’Brien, who for the past 27 months has run the office’s Criminal Division, now leads the largest United States Attorney’s Office outside of the District of Columbia. The office, which currently employs approximately 230 attorneys, serves more than 18 million residents in the counties of Los Angeles, Orange, Riverside, San Bernardino, Ventura, Santa Barbara and San Luis Obispo.

    “I am extremely pleased to be leading one of the nation’s premier public law firms,” O’Brien said after today’s swearing-in ceremony. “I look forward to maintaining this office’s long tradition of prosecuting some of the most significant cases in the nation.”

    After being unanimously confirmed yesterday by the United States Senate, O’Brien was given a four-year appointment by President George W. Bush this afternoon. O’Brien succeeds George S. Cardona, who served as the interim United States Attorney and Acting United States Attorney for nearly one year after United States Attorney Debra Wong Yang resigned to go into private practice.

    Prior to joining the United States Attorney’s Office seven years ago, O’Brien was a prosecutor in the Hardcore Gang Division of the Los Angeles County District Attorney’s Office. A 1981 graduate of the United States Naval Academy, O’Brien logged 2,000 flight hours as a radar intercept officer in F-14 “Tomcat” fighters.

    O’Brien is expected to conduct a media availability during the week of October 22. If you are interested in attending or shooting pictures at the informal event, please contact the Public Affairs Office.
