The United States Solicitor General is the person appointed to represent the federal government of the United States before the Supreme Court of the United States. The current Solicitor General, Donald B. Verrilli, Jr. was confirmed by the United States Senate on June 6, 2011 and sworn in on June 9, 2011. Verrilli's predecessor on a permanent basis, Elena Kagan, was nominated to the Supreme Court and confirmed by the Senate in August 2010. Between Kagan and Verrilli's tenures, the Principal Deputy, Neal Katyal, had served as Acting Solicitor General. The Solicitor General determines the legal position that the United States will take in the Supreme Court. In addition to supervising and conducting cases in which the government is a party, the office of the Solicitor General also files amicus curiae briefs in cases in which the federal government has a significant interest in the legal issue. The office of the Solicitor General argues on behalf of the government in virtually every case in which the United States is a party, and also argues in most of the cases in which the government has filed an amicus brief. In the federal courts of appeal, the Office of the Solicitor General reviews cases decided against the United States and determines whether the government will seek review in the Supreme Court. The office of the Solicitor General also reviews cases decided against the United States in the federal district courts and approves every case in which the government files an appeal.
