On January 20, 2021, Joseph R. Biden Jr. took the oath of office at the United States Capitol as the 46th president, having defeated incumbent Donald Trump with 306 electoral votes to 232 in the November 2020 election. At 78 years old, Biden became the oldest person inaugurated as president. The ceremony took place under heightened security following the January 6 Capitol breach. Kamala Harris was simultaneously sworn in as vice president, becoming the first woman, first Black person, and first person of South Asian descent to hold that office.
