The United States Attorney’s Office announced that Andrew B. Benson has taken the oath of office to become the U.S. Attorney for the District of Maine. U.S. Attorney Benson was nominated for the position of United States Attorney for the District of Maine by President Donald J. Trump on September 30, 2025. Attorney General Pamela Bondi appointed him U.S. Attorney effective October 22, 2025, pending Senate confirmation of his presidential nomination, and he was sworn in on the same date by U.S. District Court Chief Judge Lance E. Walker. 

U.S. Attorney Benson is the top-ranking federal law enforcement official in the District of Maine. He oversees a staff of 45 employees and contractors located in Portland and Bangor, including 21 attorneys, 21 non-attorney support personnel and three contractors. The office is responsible for prosecuting federal crimes in the district, including crimes related to terrorism, public corruption, child exploitation, firearms, and narcotics. The office also defends the United States in civil cases and collects debts owed to the United States. 

U.S. Attorney Benson was born in western Maine and grew up in Bethel, attending local schools. After high school, he attended the University of Maine at Orono and received an honors degree in German literature.  He then attended the University of Maine School of Law and received his Juris Doctorate in 1988. 

A veteran prosecutor, Benson worked for a district attorney’s office in central Maine, trying serious and violent felonies. In 1999, he was appointed one of three senior homicide prosecutors for the Maine Attorney General’s Office by Maine Attorney General Andrew Ketterer and was assigned with the responsibility of overseeing and trying homicide cases throughout the state. During his fifteen-year tenure in the Attorney General’s Office, he dealt with over 100 murder and manslaughter cases.    

In 2014, he was nominated to the bench of the Maine District Court by Governor Paul LePage. He was renominated by Governor Janet Mills in 2021. After each nomination he was unanimously confirmed by the Maine State Senate. 

While a member of the district court bench, he presided over hundreds of trials, including dozens of serious criminal jury trials. He resigned from his judicial position in order to accept the position of United States Attorney for the District of Maine.
