The Supreme Court on Monday granted U.S. Solicitor General D. John Sauer leave to join arguments in Viramontes v. Cook County (No. 25-238) and Grant v. Higgins (No. 25-566), challenges to Illinois and Connecticut bans on AR-15 and similar semiautomatic rifles. Those cases ask if the Second and Fourteenth Amendments guarantee a right to possess them, after Sauer's September 40-page amicus brief said the rifles are commonly used by law-abiding citizens for lawful purposes and bans are unconstitutional. Arguments occur December 2, 2026, with a decision expected next summer as early as June.
