2020 United States elections in the context of 2020 Republican Party presidential primaries

The 117th United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It convened in Washington, D.C., on January 3, 2021, during the final weeks of Donald Trump's first presidency and the first two years of Joe Biden's presidency and ended on January 3, 2023.

The 2020 elections decided control of both chambers. In the House of Representatives, the Democratic Party retained their majority, albeit reduced from the 116th Congress. It was similar in size to the majority held by the Republican Party during the 83rd Congress (1953–1955).

Joe Biden's tenure as the 46th president of the United States began with his inauguration on January 20, 2021, and ended on January 20, 2025. Biden, member of the Democratic Party, had previously served as the 47th vice president from 2009 to 2017 under President Barack Obama, took office after defeating the Republican incumbent president Donald Trump in the 2020 presidential election. Upon his inauguration, he became the oldest president in American history, breaking the record set by Ronald Reagan. Alongside Biden's presidency, the Democratic Party also held their majorities in the House of Representatives and the Senate during the 117th U.S. Congress following the 2020 elections, thereby attained an overall federal government trifecta. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.

Day one actions of his presidency included restoring U.S. participation in the Paris Agreement, revoking the permit for the Keystone XL pipeline and halting funding for the Mexico–United States border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days. The first major legislation signed into law by Biden was the American Rescue Plan Act of 2021, a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act, a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress to invest in American roads, bridges, public transit, ports and broadband access.

The 2020 United States House of Representatives elections in Texas were held on November 3, 2020, to elect the 36 U.S. representatives from the state of Texas, one from each of the state's 36 congressional districts. The elections coincided with the 2020 U.S. presidential election, as well as other elections to the House of Representatives, elections to the U.S. Senate, and various state and local elections. Primaries were held on March 3, and run-offs were held on July 14.

During the election cycle, a number of House races were considered vulnerable by Democrats and polls. However, in the wake of the election, Republicans were able to retain control over all of those seats. Democratic-held 15th district also became unexpectedly competitive, with incumbent representative Vicente Gonzalez attaining a narrow win over the Republican challenger. Republican wins were attributed to President Donald Trump appearing on the ballot and his unexpectedly strong support from Latino voters.
