Portland police have arrested two people outside the Portland State University campus library, as they move to clear the building, which was occupied by protesters. Police said they encountered "barricades" as they entered the building.

Individuals remaining in the building are under arrest for second-degree trespassing, police announced Thursday. The area surrounding the library has been closed off.

Police also warned that anyone resisting arrest could have force used against them and be subject to more criminal charges.

President Joe Biden addressed the nation on Thursday saying that free speech and the rule of law must both be upheld.

"We are not an authoritarian nation where we silence people or squash dissent, the American people are heard. In fact, peaceful protest is the best tradition of how Americans respond to controversial issues," Biden said, speaking from the White House.

But, he condemned the destruction of property, shutting down campuses and forcing the cancelation of classes and graduation, saying it isn't peaceful protest.

"Dissent is essential to democracy, but dissent must never lead to disorder or to denying the rights of others so students can finish the semester and their college education," Biden said.

Biden last commented on college protests on April 22 -- before there was an escalation of suspension and arrests at campuses across the country -- at the time condemning antisemitic actions and those who don't understand the plight of Palestinians in Gaza, a message he reiterated Thursday.

"There is no place for hate speech or violence of any kind whether it's anti-Semitism, islamophobia or discrimination against Arab Americans or Palestinian Americans. It’s simply wrong. There’s no place for racism in America," Biden said.

President Joe Biden, making his first remarks on the surge in protests on college campuses, said the protests have not pushed him to reconsider his policies in the region.

"Mr. President, have the protests forced you to reconsider our policies?" a reporter asked Biden Thursday.

"No," Biden said, before walking away from the podium.

At least 132 people were arrested on Thursday in protests at UCLA according to California Highway Patrol.

The University of Minnesota has reached an agreement to end the student-led encampment on campus.

The university will reopen previously closed buildings and the student coalition has pledged not to organize disruptions during final exams and the commencement ceremony.

Representatives of the student coalition will be given the opportunity to address the Board of Regents at its May 10 meeting over its call for a divestment, students will receive amnesty for their encampment, and the university will also explore an affiliation with Palestinian universities, hosting scholars at risk.

"Our meetings have been grounded in listening, learning, and respect, and I believe they were a very positive first step in reaching mutual understanding. Though the original meeting was scheduled for 30 minutes yesterday, we engaged in constructive conversation for more than 90 minutes. We then met two more times to discuss the proposed agreements," University of Minnesota interim President Jeff Ettinger said in a statement.

"We regret that these meetings did not happen sooner, and have committed to regular meetings moving forward to continue to discuss this coalition’s concerns," Ettinger said.

Ettinger also highlighted that the university supports freedom of expression as a fundamental part of its mission.

"While we do not condone tactics that are outside of our policies, we appreciate student leaders’ willingness to engage in dialogue. I value the challenging and healthy conversations we’ve had," Ettinger said.
