Karen Marston is the Administration’s fourth nominee (and first woman) tapped for the U.S. District Court for the Eastern District of Pennsylvania.
Karen Spencer Marston was born in Portsmouth, Virginia in 1968. She received a B.A. from Davidson College, an M.A.T. from Salem College and a J.D. from Wake Forest University School of Law. Marston then joined the Charlotte firm Moore & Van Allen PLLC as an Associate.
In 2000, Marston became a federal prosecutor with the U.S. Attorney’s Office for the Western District of North Carolina. She moved to the U.S. Attorney’s Office for the Eastern District of Pennsylvania in 2006 and became Chief of the Narcotics & Organized Crime branch in 2018. She serves there today.
History of the Seat
Marston has been nominated for a seat on the U.S. District Court for the Eastern District of Pennsylvania. This seat opened on September 28, 2017, when Judge Legrome Davis moved to senior status.
In February 2019, Marston applied for and interviewed with the Judicial Nomination Advisory Panel for the Eastern District of Pennsylvania. Marston then interviewed with Sen. Pat Toomey (R-Pa), Sen. Bob Casey (D-Pa), and the White House. President Trump announced Marston’s nomination to the vacancy on August 14, 2019.
Marston has spent most of her career as a federal prosecutor, primarily prosecuting drug and organized crime cases. In the course of her career, Marston has tried thirty-five jury cases, a sizable number. Notably, Marston prosecuted the drug company Novartis for marketing its drug Trileptal for off-label uses, despite only being approved by the FDA for treatment of epilepsy. In 2016, Marston also prosecuted supporters of Sen. Bernie Sanders’ presidential bid for entering a secured area during the Democratic National Convention.
Marston has been a member of the Federalist Society since 2019. Other than that, her only political involvement has been as an intern with the National Republican Committee while in college.
For better or for worse, prosecutors generally tend to be uncontroversial nominees, salable as “tough on crime.” With her record, Marston falls into this pattern and will likely be confirmed by a bipartisan majority.

The two PA senators spoke in favor of this nomination at Marston’s judiciary committee hearing. That’s not surprising.
The bigger story is that this will be the 22nd district court judge Senators Pat Toomey (R-Pa) and Sen. Bob Casey (D-Pa) will have placed on PA federal courts since 2011. They represent their constituents very well despite being a split delegation.
Quietly, these two senators have reshaped their home state’s judiciary and have done it in a mature and cooperative manner. Many other elected officials could learn a thing or two from these two senators.
