Texas Attorney General Ken Paxton has named William Peterson as the new Solicitor General of Texas. He will begin his role next month. Peterson was previously a partner and co-chair of the appellate practice at Morgan, Lewis & Bockius, LLP. He replaces Aaron Nielson, who is leaving the position after his service, as reported by the Office of the Attorney General.

Recognizing his accomplishments, General Paxton stated, "Will is one of the most accomplished lawyers in the United States, and I am confident he will do a fantastic job as Texas’s Solicitor General." His prior experience includes clerkships with a Justice Clarence Thomas of the U.S. Supreme Court and a Fifth Circuit judge. Serving Texas, Peterson is well-equipped for his new role, according to the Office of the Attorney General.

Peterson has been named the new Solicitor General of Texas, replacing Aaron Nielson. Nielson served for nearly two years and was involved in several major cases, including a Supreme Court decision requiring pornography companies to verify users' ages. He is returning to the University of Texas School of Law as a tenured professor. In a statement, Nielson said, “Serving as Texas Solicitor General has been one of the highlights of my professional life.” Attorney General Ken Paxton said, “Texas owes him a debt of gratitude for extraordinary service.” Peterson said, “I am honored to serve as Solicitor General of Texas,” as mentioned by the Office of the Attorney General.
