The inauguration took place amidst extraordinary political, public health, economic, and national security crises, including the ongoing COVID-19 pandemic; former President Donald Trump's attempts to overturn the 2020 United States presidential election, which incited an attack on the United States Capitol; Trump's second impeachment; and a threat of widespread civil unrest, which stimulated a nationwide law enforcement response. Festivities were sharply curtailed by efforts to prevent the spread of COVID-19 and mitigate the potential for violence near the Capitol. The live audience was limited; members of the Congress attended with one guest of their choosing, resembling a State of the Union address. Public health measures such as mandatory face coverings, testing, temperature checks, and social distancing were used to protect participants in the ceremony.
