The D.C. court biography states that after Bates completed his FISC term, Chief Justice Roberts, with the concurrence of the Judicial Conference, appointed him Director of the Administrative Office of the U.S. Courts, and that he served in that capacity until January 1, 2015.
Bates’s own prepared statement to the House Appropriations Subcommittee on Financial Services and General Government, dated March 26, 2014, says: “Last summer, on July 1st, the Chief Justice appointed me Director of the Administrative Office of the U.S. Courts.” He added that he had been a federal judge since 2001, had served on FISC, and had been presiding judge from May 2009 until February of the prior year.
The Federal Judicial Center lists the same office as 2013–2015 and notes board service at the FJC in those years. The Administrative Office is the judiciary’s administrative arm. The title is not a finding about FISA applications or Trump cases.
