Justice Sandra Day O’Connor, the first woman to serve on the Supreme Court, passed away at the age of 88 due to complications related to advanced dementia. Chief Justice John Roberts praised her as a “fiercely independent defender of the rule of law” and an advocate for civics education. O’Connor was appointed to the Supreme Court by President Ronald Reagan in 1981 and was a strong supporter of civics education, founding the iCivics program and advocating for students to observe oral arguments.
