OKLAHOMA CITY – The United States District Court has appointed Robert J. Troester to continue serving as the United States Attorney for the Western District of Oklahoma.  Chief United States District Judge Timothy D. DeGiusti administered the oath of office.

"I am humbled and grateful for the confidence the Court has placed in me to lead this great office in the pursuit of justice," said U.S. Attorney Troester.  "It is my sincere privilege to serve the people of the Western District with such a dedicated team of professionals who are devoted to public service and upholding the rule of law in a fair, impartial, and ethical manner." 

On December 26, 2021, Attorney General Merrick Garland appointed U.S. Attorney Troester to serve as United States Attorney.  By statute, Attorney General Garland’s appointment is limited to 120 days and expires on April 24, 2022.  The District Court’s appointment will be effective on April 25, 2022.  Thereafter, Troester will serve as United States Attorney until a presidential appointee is confirmed.

As United States Attorney, Troester serves as the chief federal law enforcement officer responsible for all federal criminal prosecutions and civil litigation involving the United States, federal agencies, and federal employees in the Western District of Oklahoma.  The Western District is the largest of three judicial districts in Oklahoma.  It includes 40 of the 77 counties and 21 federally recognized Indian tribes.  The U.S. Attorney’s Office consists of nearly 100 staff members to accomplish its mission.

U.S. Attorney Troester has served in the Department of Justice since 1995.  He has held multiple managerial positions in the U.S. Attorney’s Office throughout his career, including Acting U.S. Attorney on four occasions, First Assistant U.S. Attorney, Executive Assistant U.S. Attorney, and Chief of the Civil Division.  He has also served in other capacities in Washington D.C., including Associate Deputy Attorney General, Sr. Counsel to the Deputy Attorney General, and Deputy Director of the Executive Office for United States Attorneys. Before he joined the U.S. Attorney’s Office, Troester worked in private practice in Oklahoma City, with the State of Oklahoma government, and in local law enforcement at the Buffalo County Sheriff’s Office in Kearney, Nebraska.
