Columbia University protest escalates with students occupying building on campus

Protests took a dramatic turn at Columbia University overnight when some pro-Palestinian students occupied a building on campus. In California, police arrested 25 protesters at California State Polytechnic University who had taken over a building for about a week and shut down the campus. A similar occupation was in its third day at Portland State University. Geoff Bennett reports. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
