LOS ANGELES >> Donald Trump Jr.’s appearance today at a university to talk about his new book on liberals and free speech was marked by an argument between him and the audience over why he would not take questions, the Guardian newspaper reported .

Members of the audience of about 450 people at the University of California, Los Angeles, were vocally angry that Trump Jr. and his girlfriend, former Fox News personality Kimberly Guilfoyle, declined to take questions because of time constraints, the Guardian reported. Trump was at UCLA to promote his new book “Triggered: How The Left Thrives on Hate and Wants to Silence Us.”

After initially being greeted with shouts of shouts of “USA! USA!” when he first appeared on the stage of a lecture hall, members of the audience eventually turned to louder, openly hostile chants of “Q and A! Q and A!” after they were told he would not take questions, the newspaper reported.

The Guardian said that Trump Jr. told the audience that taking questions from the floor risked creating soundbites that leftwing social media posters would abuse and distort.

Guilfoyle told audience members that they were being rude, according to the Guardian.

Shortly thereafter, she and Trump Jr. left the stage.

Outside the lecture hall, several dozen protesters organized by the Los Angeles chapter of Refuse Fascism protested. The Los Angeles Times reports that protesters chanted “UCLA protects fascists” and “humanity first.”

Andy Stein, a supporter of President Donald Trump, told the Times that he came to UCLA to listen to Trump Jr. because he sees the son as a “chip off the old block” and admires his “feistiness.”
