Donald John Trump (born June 14, 1946) is the 45th and current President of the United States, in office since January 20, 2017. Before entering politics, he was a businessman and television personality.Trump was born in the New York City borough of Queens and earned an economics degree from the Wharton School of the University of Pennsylvania. A third generation businessman, Trump followed in the footsteps of his paternal grandmother Elizabeth Christ Trumpand father Fred Trump in running the family real estate company known since 1971 as the Trump Organization. Trump served as Chairman/President of the firm from 1971 until 2017, shortly before his inauguration as U.S. President (he still owns the company, but has given day-to-day control to his sons Donald Jr. and Eric during his presidency). Trump's business career primarily focused on building or renovating office towers, hotels, casinos, and golf courses.He also started several side ventures and branded various products with his name. He has written or co-written several books (most notably The Art of the Deal), and produced and hosted The Apprentice television series for 12 years. As of 2017, he was the 544th richest person in the world with an estimated net worth of $3.5 billion.Trump had long expressed interest in politics. He entered the 2016 presidential race as a Republican and 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 won the general election on November 8, 2016, in a surprise victory against Democratic candidate Hillary Clinton. 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 despite losing the popular vote. His election and policies sparked numerous protests.In the first months of his presidency, Trump reversed several policies of former President Barack Obama: he withdrew the United States from the Trans-Pacific Partnership and the Paris Climate Agreement, and undid parts of the Cuban Thaw. His attempt to repeal and replace the Patient Protection and Affordable Care Act ("Obamacare") was defeated in Congress. Trump appointed Neil Gorsuch to the Supreme Court. Trump ordered a travel ban on citizens from six Muslim-majority countries, citing security concerns; the ban was partially implemented after several legal challenges.[2] After Trump dismissed FBI Director James Comey, the Justice Department appointed his predecessor Robert Mueller as special counsel to investigate Russia's interference in the presidential election, potential links between Russia and Trump campaign associates, and any related matters.
