Former U.S. Solicitor General Elizabeth Prelogar has joined Cooley LLP’s legal team to represent Jenner & Block LLP in its appeal against an executive order issued by President Donald Trump. This development was disclosed in a recent court filing.
Prelogar, who previously served as the U.S. Solicitor General, rejoined Cooley in August 2025 to lead its U.S. Supreme Court and appellate practice. She expressed that the firm aligns with her professional values and offers a platform to continue her work in high-stakes appellate litigation.
The executive order in question has been a point of contention, with allegations that it was issued in retaliation against law firms representing clients and causes opposed by the president. The Trump administration announced its intention to appeal a June ruling that deemed the order unconstitutional, stating that it was issued in retaliation for the firm’s representation of clients and causes the president opposes.
Prelogar’s involvement is anticipated to bring significant expertise to Cooley’s appellate practice, particularly in cases involving constitutional challenges to executive actions. Her experience as Solicitor General and her previous tenure at Cooley are expected to be instrumental in navigating the complexities of this appeal.
The legal community is closely monitoring this case, as it addresses critical issues regarding executive authority and the independence of legal representation. The outcome could have far-reaching implications for the relationship between the executive branch and the legal profession.
