The 2020 presidential election was one of the most historic, contested, and contentious in American history. Joe Biden was the oldest person elected President. Kamala Harris was the first female elected Vice President, and the first Vice President of Black and Asian descent. The primaries, campaigns, and elections were held for the first time amid an international and national pandemic. Despite this, voter turnout was the highest in 120 years. Donald Trump was the first president in modern times refusing to concede, leading to numerous lawsuits over the election process and results, although election litigation and state officials found no evidence of large-scale voter fraud. Nevertheless, continued claims of a stolen election led to a riotous mob occupation of the United States Capitol on January 6, 2021, in an attempt to overturn the Electoral College results.
