Supreme Court Chief Justice John Roberts on Tuesday selected Judge Merrick Garland, who was nominated to the Supreme Court by former President Barack Obama, to serve as chairman of the Executive Committee of the Judicial Conference of the United States. The chief judge of the D.C. Circuit Court of Appeals will oversee the committee responsible for heading the policy-making body of the federal court system. Roberts is the presiding officer of the conference and selected Garland to run the "senior executive arm" of the conference, which makes recommendations to Congress regarding legislation involving the judiciary.
