Career and documented accomplishments

• Her career includes Justice Department Office of Legal Counsel and associate deputy attorney general roles, teaching at George Mason and Catholic University, and founding Catholic University’s Separation of Powers Institute. [1]
• The Senate confirmed PN466-4 by 50 votes to 47; PN25-31 for Education general counsel was withdrawn on September 2, 2025. [2] [3]

Role and nomination context

• The university describes the Third Circuit’s coverage of Delaware, New Jersey and Pennsylvania. Its announcement identifies the judge using the shorter Jennifer Mascott name, supporting an alias rather than a separate biography. [4]
• The FJC records the distinct judicial path: confirmation on October 9, 2025 and commission on October 10. The two name variants are supported by the university’s accounts of both nominations, not merely by matching names. [1] [4]
