Columbia University Threatens To Expel Students As Protests Intensify

Columbia University says student protesters who barricaded themselves inside a campus building "face expulsion". Police in riot gear have moved in to break up protests and made dozens of arrests. Demonstrators at the New York campus escalated their protest over the war in Gaza by smashing into and occupying Hamilton Hall overnight.
