Donald Trump Jr. tried to address a crowd of more than 800 people at UF on Thursday evening.

Instead, he found himself bickering with protesters in the audience.

UF ACCENT Speakers Bureau hosted Trump Jr. and Kimberly Guilfoyle — his girlfriend and a senior adviser on President Donald Trump’s 2020 campaign — in a keynote presentation on Thursday night at the University Auditorium.

ACCENT paid both speakers a total of $50,000, which comes from $19.06 per credit hour students pay each semester.

ACCENT originally scheduled a 15-minute Q&A, but became nervous of protestors hijacking the microphone, said Cameron Gittler, assistant director of productions. The speakers selected questions from a Twitter hashtag instead.

Trump Jr. highlighted some of the accomplishments of his father’s administration, such as the declining number of Americans on food stamps and record-low unemployment rates for minorities. He also mentioned the danger that socialism and communism brought to countries such as China and Venezuela.

He occasionally stopped speaking to confront protesters yelling over him.

“What is interesting about ideas is that your ideas can’t be all that good if you’re not willing to let other people speak theirs,” Trump Jr. said.
