Attorney General Jeff Sessions is set to deliver a speech on how freedom of speech is “under attack” in American colleges and universities on Tuesday. The address takes aim at the rise of political correctness and safe spaces.

Sessions’ statements will come following an almost year-long series of confrontations started by leftist student activists against right-wing speakers throughout colleges in the United States. According to an advance provided to Fox News, Sessions plans to highlight the suppression of free speech and the prevalence of ideological “echo chambers.”

“Freedom of thought and speech on the American campus are under attack,” Sessions plans to say in his speech, which he will deliver at Georgetown University Law Center. “Whereas the American University was once the center of academic freedom — a place of robust debate, a forum for the competition of ideas — it is transforming into an echo chamber of political correctness and homogenous thought, a shelter for fragile egos.”

His remarks come amid an increasingly tense climate across American campuses, which has only been exacerbated by Trump’s inauguration into the White House. This February, antifa riots at the University of California, Berkeley prompted the university to cancel a speaking engagement by Milo Yiannopoulos. In April, Ann Coulter was forced to cancel her speech after losing her backing, also at UC Berkeley. American Enterprise Institute scholar Charles Murray and the professor who hosted his speech at Middlebury College, Allison Stanger, were both assaulted by left-wing protesters.
