A fire destroyed the home of South Carolina Circuit Court Judge Diane Goodstein weeks after she temporarily blocked South Carolina from handing over millions of voters’ personal data to Trump’s DOJ. She received death threats following that ruling. Goodstein was unharmed. Three family members, including her husband, were hospitalized. Authorities are investigating possible arson; a cause has not yet been determined.
