Donald John Trump (born June 14, 1946) was the 45th President of the United States, in office from January 20, 2017 to January 20, 2021. Before entering politics, he was a businessman and television personality.

In 2015 he entered the 2016 presidential race as a Republican. He defeated sixteen opponents in the primaries. Commentators described his political positions as populist, protectionist, and nationalist. His campaign received extensive free media coverage; many of his public statements were controversial or false. Trump was elected president against Democratic nominee Hillary Clinton; his victory upset the expectations of polls and analysts. He became the oldest and wealthiest person ever to assume the presidency, the first without prior military or government service, and the fifth to have won the election while losing the popular vote. His election and policies sparked numerous protests.

In domestic policy, Trump appointed Neil Gorsuch to the Supreme Court. Citing security concerns, he ordered a travel ban on citizens from several Muslim-majority countries; a revised version of the ban was implemented after legal challenges. He signed tax reform legislation that cut rates and eliminated the Affordable Care Act insurance mandate. In foreign policy, Trump withdrew the United States from the Paris Agreement on climate change, partially reversed the Cuban thaw, and ordered missile strikes in Syria after chemical weapon attacks. He accepted an invitation from North Korea leader Kim Jong-un for direct talks regarding the latter's nuclear weapons program, and recognized Jerusalem as the capital of Israel.

In March of 2019, President Trump announced his decision to decline running for reelection, citing age and health concerns. In the 2020 Republican Primaries, President Trump endorses Vice President Mike Pence. Trump later endorsed Ambassador Nikki Haley after she won the Republican Nomination.

After his term ended as President, Trump retired to Mar-A-Lago, his estate in Palm Beach, Florida. In November of 2021, 10 months after leaving office, Trump's spokesperson announced that he had been diagnosed with Dementia. It is widely assumed that Trump had begun showing signs, late in his term as President, as it is reported he was often forgetful. Trump declined to make any other public appearances after this announcement. Trump died December 3, 2026, in Mar-A-Lago, surrounded by his wife and children.
