Donald John Trump (standard pronunciation; born June 14, 1946) is an American businessman, politician, television personality, author, and the presumptive nominee of the Republican Party for President of the United States in the 2016 election. He is chairman of The Trump Organization, which is the principal holding company for his real estate ventures and other business interests. Trump worked for his father’s real estate development firm while attending college. After graduating from the Wharton School of the University of Pennsylvania in 1968, he joined the company and in 1971 was given control, later renaming it The Trump Organization. He has since built casinos, golf courses, hotels, a New York City neighborhood, and other real estate properties, many of which bear his name, and founded Trump Entertainment Resorts (now owned by Carl Icahn). He has also made branding deals that feature his name on properties in which he has minority or no ownership. Listed by Forbes as one of the world’s wealthiest people, Trump and his businesses, as well as his three marriages, have received prominent media exposure. He hosted The Apprentice, a popular NBC reality television show, from 2004 to 2015. Trump first campaigned for the U.S. presidency in 2000, and withdrew before any votes were cast, but still won two Reform Party primaries. On June 16, 2015, he again announced his candidacy for president, as a Republican. Trump became known for supporting measures to reduce illegal immigration, for opposing various free-trade agreements that he regards as unfair, for his frequently non-interventionist views on foreign policy, and for his idea to temporarily ban most foreign Muslims from entering the United States until Congress can determine how to address Islamic terrorism. Trump quickly emerged as the front-runner for the Republican nomination. His remarks and positions have inspired protests both opposing and supporting him. Trump’s victories—culminating with the Indiana primary—led his remaining Republican rivals to suspend their campaigns, whereupon Republican chairman Reince Priebus declared Trump the party’s presumptive presidential nominee. A few weeks later, on May 26, 2016, the Associated Press reported that Trump had gained the 1,237 delegates needed to secure the Republican nomination.
