Andrew has substantial experience in criminal law. Most recently, he served as a law clerk in the U.S. Attorney’s Office for the District of Maryland. He drafted the brief for the United States in the Fourth Circuit criminal case United States v. Tyson and provided key legal research for sentencing issues in two other Fourth Circuit briefs. His other assignments included investigating whether the facts of a particular case supported a potential indictment under the Travel Act.

As a student attorney in the University of Maryland Immigration Clinic, Andrew advised public defenders from across Maryland on the immigration consequences of their clients’ criminal matters. The Clinic’s work in this area filled a critical gap in the capabilities of the Maryland Office of the Public Defender following the Supreme Court’s decision in Padilla v. Kentucky.

As an intern with the State’s Attorney’s Office of Montgomery County, Maryland in 2004, Andrew pulled files for upcoming District Court cases and called witnesses to remind them of upcoming trial dates. He spent dozens of hours observing court proceedings. He also assisted a prosecutor in daily bond review hearings.

Andrew took his law school’s required criminal law course and studied criminal procedure in an elective course taught by Judge Andre Davis.

In July 2008, the Baltimore Sun published Andrew’s letter to the editor questioning the priorities of the Maryland State Police.
