Donald John Trump (born June 14, 1946) is an American politician, media personality, and businessman who served as the 45th president of the United States from 2017 to 2021. Having won the 2024 presidential election as the nominee of the Republican Party, he is the president-elect and will be inaugurated as the 47th president on January 20, 2025.

Trump graduated with a bachelor's degree in economics from the University of Pennsylvania in 1968. Becoming president of the family real estate business in 1971, he focused on luxury accommodation. After a series of business bankruptcies in the 1990s, he launched side ventures. From 2004 to 2015, he produced and hosted the reality television series The Apprentice.

Trump won the 2016 presidential election as the Republican nominee. His immigration policy included ordering a travel ban on several Muslim-majority countries, expanding the U.S.–Mexico border wall, and implementing a family separation policy. He rolled back more than 100 environmental policies and regulations, signed the Tax Cuts and Jobs Act of 2017, and nominated Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett to the U.S. Supreme Court. In 2018, he initiated a trade war with China. He withdrew the U.S. from international agreements on climate, trade, and the nuclear program of Iran. He met with North Korean leader Kim Jong Un without progress on denuclearization. In response to the COVID-19 pandemic, he downplayed its severity, contradicted guidance from international public health bodies, and signed the CARES Act economic stimulus. He was impeached in 2019 for abuse of power and obstruction of Congress, and in 2021 for incitement of insurrection; the Senate acquitted him in both cases.

Trump's politics and rhetoric led to the Trumpism movement. Many of his comments and actions have been characterized as racially charged, racist, and misogynistic. He promoted conspiracy theories and made false and misleading statements during his campaigns and presidency, to a degree unprecedented in American politics. After his first term, scholars and historians ranked him as one of the worst presidents in American history. He lost the 2020 presidential election but did not concede, falsely claiming widespread electoral fraud and attempting to overturn the results, including through his involvement in the January 6 Capitol attack. In civil proceedings, Trump was found liable for sexual abuse and defamation in 2023, and financial fraud in 2024. In May 2024, he was found guilty of falsifying business records, making him the first U.S. president to be convicted of a felony. He faced more felony indictments related to his interference in the 2020 election and his handling of classified documents, which were dismissed after his victory in the 2024 election.
