President Donald Trump is speaking out against recent protests at a Southern Tier college.

WBNG-TV reports Binghamton University students protested last month when conservative economist Art Laffer spoke on campus, causing the event to be shut down. Two students were arrested in the incident, which came a day after 200 protesters objected to the BU College Republicans Group and Turning Point USA setting up “provocative displays” on tables outside the University Union building.

According to the Press-Sun Bulletin, the tables promoted Laffer’s lecture on “Trump, Tariffs and Trade Wars” and displayed pro-gun signs, hours after a shooting at a Santa Clarita high school in California. University police responded to the scene to prevent escalation, BU said; no violence or injuries occurred, but heated exchanges were shared on right-wing sites and social media pages.

Trump referred to the protests in a speech at the Turning Point USA Student Action Summit this past week, saying Laffer was surrounded by hundreds of “radicals” who “swing clubs, they swing bats, they swing everything.”

“A mob flooded the place wearing masks and red arm bands and acted tough,” Trump continued. “Take the mask off, take their jackets off, you’ll see their arms are about this big," he added, suggesting their arms were skinny.

Spectrum News said it was at Binghamton University when the protest occurred, and their cameras didn’t capture any of the images described by the president.

Trump invited Lacey Kestecher, a freshman at Binghamton University, to speak on stage at the conservative conference held Saturday in West Palm Beach, Fla.

“Really, what we need to do is we need to bring back freedom of speech on our campuses. We cannot let these radical leftists continue to suppress our speech,” Kestecher said.

“Conservatives and patriots cannot and must not surrender our cherished institutions and culture to the radical, America-hating left," Trump added. “Our nation badly needs more young people like those here tonight to study up, work hard, and then go into government, go into journalism, go into media, go into teaching, and yes, go into academia and retake these institutions, rebuild our culture and take back our country.”

A clip of the segment was posted on YouTube by the New York Federation College Republicans, which called the protesting students “antifa thugs.” The full speech is available on the White House YouTube channel.

Binghamton University, also known as SUNY Binghamton, is a public school that’s part of the State University of New York system.

Dr. Arthur Laffer, who served as an economic adviser to the late President Ronald Reagan and to Trump’s 2016 campaign, received the Medal of Freedom from President Trump earlier this year. Laffer is best known for the “Laffer Curve,” which suggests taxation rates beyond a certain level can be counterproductive by discouraging work and is frequently cited by Republicans in favor of tax cuts, and wrote the 2016 book “Trumponomics: Inside the America First Plan to Revive Our Economy.”
