The United States Studies Centre event was held at Manning Bar from 11am.
When organisers became aware of the inappropriate behaviour of some attendees the University of Sydney Union’s security team intervened to remove several participants and issue warnings to others.
The official event ended at 3pm and some students and members of the public remained to watch the coverage.
The University of Sydney and University of Sydney Union expect students to abide by the code of conduct and any behaviour that is intimidating, abusive, disrespectful, or threatening will not be tolerated within our community or on our campuses.
