WESTCHESTER COUNTY – The Westchester County District Attorney’s Office is proud to have hosted 50 college and law school students representing 33 colleges and universities across the country for their 2023 summer internship. The eight-week program, led by Chief Development & Training Officer Jackie Halper, provided an opportunity for the interns to experience all aspects of prosecutorial work, training on the law and participation in mock trials (always a highlight), which were conducted with DA Rocah and ADAs as judges, in the County Board of Legislators chambers.
