Legal experts say they expect the new U.S. Attorney for Massachusetts to be closely aligned with the Department of Justice's priorities: immigration and drug trafficking.

Longtime federal prosecutor Leah Belaire Foley is the new U.S. Attorney in Massachusetts. Foley, who previously served as Assistant U.S. Attorney, was sworn in to her new role on Tuesday afternoon, one day after her appointment as U.

Leah Foley is currently deputy chief of the narcotics and money laundering unit and has prosecuted high-profile drug trafficking and sex trafficking crimes.

The new U.S. Attorney for Massachusetts could bring a sharper focus on federal immigration and drug cases, according to a legal expert.

Acting Attorney General James McHenry has appointed Assistant U.S. Attorney Leah Belaire Foley as the United States Attorney for the District of Massachusetts.
