• Donald Trump once slapped his son, Don Jr. in school 
  • The PTUS knocked down his son in school 
  • Donald Trump's temper is reportedly very bad

Donald Trump was unable to control his temper at the sight of his son, Donald Jr., decades ago.

Scott Melker, a DJ and realtor, shared details from his previous encounter with the POTUS back in college at the University of Pennsylvania.

Melker revealed in his lengthy Facebook post that he and Don Jr. lived in the same freshman dorm at the university. On one occasion, the president picked up his son before watching a baseball game together.

When the POTUS saw that Don Jr. was wearing a Yankees jersey, he reportedly became upset and slapped him on the face. Melania Trump’s husband was not pleased with how his son dressed because he felt that it wasn’t appropriate for the occasion.

“Don Jr. opened the door, wearing a Yankee jersey. Without saying a word, his father slapped him across the face, knocking him to the floor in front of all of his classmates. He simply said, ‘put on a suit and meet me outside,’” he wrote.

Melker also said that based on what he saw, he doesn’t think that Trump has the basic social decency to serve as the head of the country.

Meanwhile, the POTUS and Don Jr. were reportedly never close. In fact, their relationship only improved after the president was able to talk business with his son.

While speaking with the New York Magazine years ago, Don Jr. revealed that his life was influenced more by his grandparents than his own father.

“My father is a very hardworking guy, and that’s his focus in life, so I got a lot of the paternal attention that a boy wants and needs from my grandfather,” he said.

Don Jr. also refused to talk to Trump for an entire year after his affair with Marla Maples was made public. But according to the POTUS’s son, he immediately sided with his mom, Ivana Trump, because he lived with her and it was easy to get a one-sided perspective on the matter.
