University administrators from Texas to California moved to clear protesters and prevent encampments from taking hold on their own campuses as they have at Columbia University, deploying police in tense new confrontations that already have led to dozens of arrests.

At the same time, new protests continued erupting in places like Pittsburgh and San Antonio. Students expressed solidarity with their fellow students at Columbia, and with a pro-Palestinian movement that appeared to be galvanized by the pushback on other campuses and the looming end of the academic year.
