Donald John Trump (born June 14, 1946) is an American politician, media personality, and businessman who is the 47th president of the United States. A member of the Republican Party, he served as the 45th president from 2017 to 2021.

Born into a wealthy family in New York City, Trump graduated from the University of Pennsylvania in 1968 with a bachelor's degree in economics. He became the president of his family's real estate business in 1971, renamed it the Trump Organization, and began acquiring and building skyscrapers, hotels, casinos, and golf courses. He launched side ventures, many licensing the Trump name, and filed for six business bankruptcies in the 1990s and 2000s. From 2004 to 2015, he hosted the reality television show The Apprentice, bolstering his fame as a billionaire. Presenting himself as a political outsider, Trump won the 2016 presidential election against Democratic Party nominee Hillary Clinton.

During his first presidency, Trump imposed a travel ban on seven Muslim-majority countries, expanded the Mexico–United States border wall, and enforced a family separation policy on the border. He rolled back environmental and business regulations, signed the Tax Cuts and Jobs Act, and appointed three Supreme Court justices. In foreign policy, Trump withdrew the U.S. from agreements on climate, trade, and Iran's nuclear program, and initiated a trade war with China.
