A Federal Public Defender is a lawyer appointed by the federal government to represent individuals who cannot afford to hire their own attorney in criminal cases. These defenders work within the Federal Public Defender's Office, which operates in various districts across the United States. Their primary role is to ensure that defendants receive fair legal representation, as guaranteed by the Sixth Amendment of the U.S. Constitution. Federal Public Defenders handle a range of cases, including serious offenses like drug trafficking and fraud. They are skilled legal professionals who advocate for their clients in court, negotiate plea deals, and provide legal advice throughout the judicial process.
