The U.S. Supreme Court will hear arguments Wednesday in a case involving a former Castle Hills councilwoman who alleges she was arrested in retaliation for speaking out against the San Antonio suburb’s city manager. Slate Magazine last month described the widely watched case as being among the “most disturbing First Amendment cases of the decade so far.” The legal fight stems from the arrest of retiree Sylvia Gonzalez, now 72, who won a Castle Hills City Council seat in a tightly contested 2019 race.
