The criminal division chief of the Eastern District U.S. Attorney’s Office has been tapped as the top deputy for the U.S. Department of Justice’s criminal division.

Marshall Miller has been named the second-in-command for the justice department’s criminal matters. Marshall would be deputy to Leslie Caldwell, a partner with Morgan, Lewis & Bockius, who has been nominated as Assistant Attorney General for the Criminal Division and awaits U.S. Senate confirmation.

Miller, 42, worked as a prosecutor in the Eastern District’s office from 1999 to 2003. After three years teaching at New York University School of Law, Miller re-joined the office in 2006 and became its criminal division chief in November 2011. He left last week for his new role in Washington, D.C., acting principal deputy assistant attorney general and chief of staff.

While in the Eastern District, Miller was involved in a range of cases, from corporate fraud and public corruption matters to the prosecution of violent gang members, terrorists and recently, two defendants convicted of plotting to kill an Eastern District judge and prosecutor. He is a Yale Law School graduate admitted to the bar in 1999.

A spokesperson for the Eastern District U.S. Attorney said Miller’s replacement has not yet been announced.
