Two days after his speech at Northwestern, Mr. Sessions, a Republican, formally announced that he was entering the Senate race in Alabama. He emphasized his loyalty to President Trump, who forced him from office a year ago after Mr. Sessions recused himself from overseeing the Justice Department’s investigation into whether Mr. Trump and his associates worked illegally with Russians to interfere in the 2016 election.
President Trump has made fighting political correctness and pushing boundaries central to his identity. The issue of free speech on college campuses has become a rallying cry to some of his supporters, including many young conservative activists, who point to instances around the country in which conservative viewpoints — and appearances by conservative speakers — have been shunned or protested by liberal students and professors.
In 2018, during Mr. Sessions’s contentious 21-month tenure at the Justice Department, he announced the administration’s so-called zero-tolerance policy, which led to thousands of family separations along the United States’ border with Mexico.
In an article Wednesday about Mr. Sessions’s speech, The Daily reported that it was interrupted multiple times by demonstrators who pounded on the door of the auditorium where Mr. Sessions was speaking and recited phrases including: “You are a racist; you put kids in cages.”
Another article on Wednesday focused on the protests spurred by the event. It mentioned that university police officers had blocked protesters from entering the venue, and it quoted demonstrators, including a protester who said, “There’s a difference between having a sustained dialogue and listening to other opinions and accepting hate speech and fascism.”
On Friday, The Daily reported, Morton O. Schapiro, the president of the university, said that unlike some institutions, Northwestern does not grant amnesty to student protesters. “You can protest, you can’t hurt anybody and you can’t shut down speech,” he said. “And if you do, you’re going to face the consequences.”
He also questioned whether it had been a good idea to invite Mr. Sessions instead of a different conservative speaker, adding that the episode had been “polarizing.”
