The team has produced a number of Olympians, including five in 2012.^[4] Columbia grad Alen Hadzic was named as an alternate to the 2021 Olympic team, but was suspended by the United States Center for SafeSport (SafeSport) due to findings of an investigation following allegations of rape and other sexual misconduct; an arbitrator later reduced his sanction, allowing him to go to Tokyo, though he did not fence.^[5][6][7][8] Hadzic had previously been suspended by Columbia University for a year for sexual misconduct, while he was a member of the Columbia team, as a result of the findings of a Title IX investigation.^[9][5] In June 2023, Hadzic was banned from fencing in the US for life by SafeSport, due to his sexual misconduct.^[10][11]
