U.S. Solicitor General Donald Verrilli—who defended the Affordable Care Act in several major Supreme Court cases—will step down as of June 24. His principal deputy, Ian Gershengorn, will replace him as acting solicitor general.
Verrilli, 58, argued for the government in King v. Burwell last year, a case over the legality of the ACA's insurance premium subsidies. The court ruled 6-3 to uphold the subsidies for Americans in all states. He also represented the government in National Federation of Independent Business v. Sebelius, a 2012 case in which the court upheld the ACA's requirement that all Americans be insured or pay a penalty. The court also ruled that states couldn't be forced to expand Medicaid coverage.
