Earlier this month, President Trump nominated Andrew Lelling to become the United States Attorney for the District of Massachusetts. If his nomination is confirmed by Congress, Lelling will oversee a staff of roughly 200 people that handles hundreds of federal criminal cases each year, including many high-profile ones. WGBH's Morning Edition anchor Joe Mathieu spoke with WGBH News legal analyst and Northeastern University law professor Daniel Medwed about Lelling’s nomination and how history will view former U.S. Attorney Carmen Ortiz’s tenure.
