Biden, 78, has become the oldest US president in history, ending one of the most dramatic political transitions in American history. He was sworn in at a scaled-back ceremony in Washington due to coronavirus and security concerns following the January 6 assault on the US Capitol by Trump supporters. Creating history, Kamala Harris, the daughter of immigrants from Jamaica and India, has become the first Black person, first woman, and first Asian American to serve as vice president. Donald Trump is the first president who did not attend his successor’s inauguration since 1869.
