COVID-19 changed nearly every part of American life in 2020. The first reported US case came in January, and by March community transmission was established. States closed schools and businesses, hospitals faced waves of patients, and millions of people shifted to remote work or lost jobs. Congress passed the $2.2 trillion CARES Act to support households, employers, health systems and unemployment programs. By year's end, the United States had reported hundreds of thousands of deaths and the first vaccine doses were being administered under emergency authorization.
The murder of George Floyd by a Minneapolis police officer on May 25 brought mass demonstrations against racism and police violence. Protests spread to communities large and small, joined by debate over public safety, monuments and institutional discrimination. In June, the Supreme Court ruled in Bostock v. Clayton County that federal employment law protects gay and transgender workers. Justice Ruth Bader Ginsburg died in September, and the Senate confirmed Amy Coney Barrett eight days before the election.
The presidential campaign unfolded through the pandemic, record early voting and intense disputes over election administration. Joe Biden defeated President Donald Trump with 306 electoral votes and more than 81 million popular votes. Trump and allies challenged the result, but recounts, audits and court rulings did not overturn it. Away from politics and illness, SpaceX's Crew Dragon carried astronauts from US soil to orbit, the Los Angeles Dodgers won a neutral-site World Series, and Parasite became the first non-English-language film to win the Academy Award for Best Picture.
