Context: Elizabeth Christ Trump (born Elisabeth Christ; October 10, 1880 – June 6, 1966) was a German-born American businesswoman and is considered the matriarch of the Trump family.  She married Frederick Trump in 1902.  While raising their three children, the early death of her husband in 1918 required her to manage his properties in order to support her family.  She founded the real estate development company Elizabeth Trump & Son with her son Fred.  The company, now known as The Trump Organization, is currently owned by her grandson, Donald Trump, who is the 45th President of the United States.  Her great-grandsons, Donald Trump Jr. and Eric Trump are running the family business as trustees during their father's presidency. Trump National Golf Club Westchester is a private golf club in Briarcliff Manor, New York.  Owned by Donald Trump, the 45th President of the United States, the 140 acre course has eighteen holes, with a 75000 sqft clubhouse.  Founded in 1922 as "Briarcliff Country Club", it later operated as "Briar Hills Country Club" and "Briar Hall Golf and Country Club" before Trump's purchase of the property in 1996.  Trump renamed the club to match his other golf properties, and after its county, Westchester.  He had the clubhouse and course rebuilt for its 2002 reopening; the course was designed by Jim Fazio.  Donald Trump served as president over Trump National Golf Club LLC (managing the Westchester club) from August 2000 until January 19, 2017, the day before his inauguration. Patrick Joseph Buchanan ( ; born November 2, 1938) is an American conservative political commentator, author, syndicated columnist, politician and broadcaster.  Buchanan was a senior advisor to U.S. Presidents Richard Nixon, Gerald Ford and Ronald Reagan, and was an original host on CNN's "Crossfire".  He sought the Republican presidential nomination in 1992 and 1996.  He ran on the Reform Party ticket in the 2000 presidential election. Donald Trump's presidential campaign of 2000 for the nomination of the Reform Party began when real estate magnate Donald Trump of New York announced the creation of a presidential exploratory committee on the October 7, 1999 edition of "Larry King Live".  Though Trump had never held elected office, he was well known for his frequent comments on public affairs and business exploits as head of The Trump Organization.  He had previously considered a presidential run in 1988 as a Republican, but chose not to run.  For 2000, Minnesota Governor Jesse Ventura persuaded Trump to seek the presidential nomination of the Reform Party, which was fracturing despite achieving ballot access and qualifying for matching funds as a result of the 1996 presidential campaign of businessman Ross Perot.  Trump's entrance into the Reform Party race coincided with that of paleoconservative commentator Pat Buchanan, whom Trump attacked throughout the campaign as a "Hitler-lover." Donald Trump was elected President of the United States on November 8, 2016 and was inaugurated on January 20, 2017.  He is currently serving his day in office.

The following articles cover the timeline of the presidency of Donald Trump: "Donald Trump" is a song by American rapper/singer Mac Miller, and the only song released as an official single from his mixtape "Best Day Ever".  The melody, which is played throughout the song, is taken from "Vesuvius" by Sufjan Stevens.  The music video to the song was uploaded to YouTube on March 3, 2011, while the single was released digitally on May 17, 2011.  "Donald Trump" is also incorrectly included as a bonus track on the track list of some versions of Mac Miller's debut album "Blue Slide Park".  Miller himself confirmed that the song does not feature on the album.  The song was dedicated to the American business magnate Donald Trump, who, five years after the song's release, was elected as the 45th President of the United States.  During Trump's 2016 campaign, the song regained popularity, hitting #28 on the iTunes Charts on November 9, 2016, the day after he was elected president.  However Mac Miller has personally stated in an interview that he was not a supporter of Trump. Donald Trump has pursued business deals in Russia since 1987, and has sometimes traveled there to explore potential business opportunities.  In 1996, Trump trademark applications were submitted for potential Russian real estate development deals.  Trump's partners and children have repeatedly visited Moscow, connecting with developers and government officials to explore joint venture opportunities.  Trump was never able to successfully conclude any real estate deals in Russia.  However, individual Russians have invested heavily in Trump properties, and following Trump's bankruptcies in the 1990s he borrowed money from Russian sources.  In 2008 his son Donald Trump Jr. said that Russia was an important source of money for the Trump businesses. Anthony Senecal is the ex-butler of Donald Trump, and is currently employed as the "in house historian" and tour leader at Trump's private club and part-time residence, Mar-a-Lago.  He entered the public spotlight in 2016 when numerous Facebook posts he made were exposed by "Mother Jones".  They included calls for executing Barack Obama and Hillary Clinton.  Senecal endorsed Donald Trump for president.  Trump called Senecal's remarks "disgusting", adding that "Mr. Senecal is obviously a very troubled man.”  Trump's campaign also disavowed Senecal's views when they were made public, but Senecal was allowed to continue conducting tours at the Trump property in Florida. Trump Winery (formerly Kluge Estate Winery and Vineyard) is a Virginia winery situated on Trump Vineyard Estates in Charlottesville, Virginia.

It is currently run by Trump's son Eric, under the name Eric Trump Wine Manufacturing LLC.  Trump Winery manufactures 36,000 cases of wine per year.  Donald Trump has referred to it as "one of the largest wineries in the United States", although it actually ranks behind two other Virginia wineries that produce at least 60,000 cases of wine per year.
