US billionaire Donald Trump officially secured the 2016 Republican Party presidential nomination at the GOP convention in Cleveland, Ohio on July 19.
The House Speaker, Paul Ryan, urged delegates to unite behind Mr Trump, a day after splits in the party were evident as the convention opened.
Trump and his running mate Indiana Governor Mike Pence will now face Democratic presidential nominees Hillary Clinton and her running mate Virginia Senator Tim Kaine on November 8.
The property baron-turned-reality TV star faced 17 candidates in the 2016 Republican presidential primaries and caucuses that culminated in the July 18-21 national convention.
Trump emerged as the presumptive Republican nominee by May 4 due to a series of victories, starting with the Iowa caucuses and continuing through the New Hampshire primary, South Carolina, Super Tuesday, and the Indiana primaries.
“It is my honor to be able to throw Donald Trump over the top in the delegate count tonight with 89 delegates,” Donald Jr. said, surrounded by three of Trump’s other children – Ivanka, Eric, and Tiffany.
Trump later tweeted “Such a great honor to be the Republican Nominee for President of the United States. I will work hard and never let you down! AMERICA FIRST!”
