The sentence says Trump stopped extracurriculars after freshman year, but multiple sources place him in extracurricular activities during sophomore year at Fordham:

• The NCAA says Trump "spent the first two years of his college career at Fordham" and that he "joined the tennis team in the spring of his sophomore year."
• The Fordham Ram reports Trump was on the squash team as a freshman and that he quit ROTC during his sophomore year, which also means his extracurricular participation extended beyond freshman year.

So the claim is too absolute: even if his extracurricular involvement was limited, it did not end after freshman year.

This claim places Trump's transfer to Wharton early in his sophomore year, but the available school and athletics sources say he remained at Fordham for two full academic years and transferred only afterward.

• The NCAA says Trump "spent the first two years of his college career at Fordham" and only after two seasons of squash and one season of tennis "would transfer to Penn."
• The Fordham Ram likewise states that Trump attended Fordham for his first two years of college before transferring to the University of Pennsylvania.

That means he did not transfer early in sophomore year. At most, sources say he was planning or seeking a transfer during sophomore year; the actual transfer happened later.

Fordham's own history shows that its football program was not Division III during Trump's years there.

• Fordham Now says students won approval to restart football in September 1964, and that the team that played that fall was a "newly formed club football team."
• Fordham Athletics likewise says that when the administration rejected bringing back varsity football, students created a club team that was "student coached, student funded and student run."

So describing the mid-1960s team as a "Division III football club" mixes together two different eras: the team was a club team in 1964, while Fordham returned to varsity football later and only reached the Division III level afterward.
