Donald Trump taught his children to fight dirty and win, no matter the cost.
Decades before Donald Trump Jr. started making headlines as a First Son with a controversial record of meeting with Russian nationals, President Donald Trump‘s eldest child was a self-confessed hard-partying fraternity brother at the University of Pennsylvania.
There, Donald Trump Jr. was so notorious for his strong interest in women that a friend who went to frat parties with him tells PEOPLE in this week’s cover story: “Everyone was warned to stay away from Donnie Trump.”
It’s a warning that reverberates with similarities to the reputation his father built long outside of college.
At his father’s alma mater, the Wharton School at Penn, Don Jr.’s reputation also included getting into “drunken, ‘do-you-have-any-idea-who-I-am?’ fights,” according to a 2004 profile in New York magazine.
“To be fairly candid, I used to drink a lot and party pretty hard,” Don Jr. admitted in the 2004 interview. “And it wasn’t something that I was particularly good at. I mean, I was good at it, but I couldn’t do it in moderation.”
In another account of Don Jr.’s college years, Scott Melker, a former Penn classmate, wrote on Facebook: “Donald Jr. was a drunk in college. Every memory I have of him is of him stumbling around on campus falling over or passing out in public, with his arm in a sling from injuring himself while drinking.”
Regarding his past drinking, a source who worked for the Trump family tells PEOPLE: “‘There is a lot of impulsive behavior in the family.”
After graduating, Don Jr. initially declined to join the family business, instead moving to Aspen, Colorado, where he hunted, fished, camped, lived out of the back of a truck, and bartended, according to Vanity Fair — which also reported that Don Jr. stopped talking to his father during this time.
