Donald J. 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.  He took over his family’s real estate business in 1971, renamed it The Trump Organization, and expanded it to involve the construction and renovation of skyscrapers, hotels, casinos, and golf courses.  Trump also started various side ventures, including branding and licensing his name for real estate and luxury consumer products.  He co-authored several books, including The Art of the Deal; and from 2003 to 2015, he was a producer and the host of The Apprentice, a reality television game show.  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 despite losing the popular vote.  (More from Wikipedia)
