While Ivanka Trump is the first daughter of Donald Trump, his firstborn is successful son Donald Trump Jr., who takes after his name. Born to Donald and his first wife Ivana Trump, Don Jr. has built a career and respectable aura around his status as a powerful and accomplished Trump. Tonight at the RNC along with his half-sister Tiffany, Trump’s first son will take the stage to advocate his father’s presidency.

Don Jr. was educated at the University of Pennsylvania, where he gained a B.S. degree. He then went on to become an esteemed real estate developer at the Trump Organization, and now shares the Executive Vice President position with Ivanka. He was also a frequent guest judge on the Apprentice.

Trump married model Vanessa Haydon, and has five children, including a son also named Donald Trump III. Don Jr. plans to instill in his children a fierce loyalty to family like his father has.

As the campaign trail continues firing up, Don Jr. continues to make public appearances on his father’s behalf.
