There's A Massive Sexual Assault March Happening At Columbia University

Hundreds of Columbia University students are rallying by carrying mattresses today to support sexual assault survivors.

The Columbia students are joining student activists around the world in a #carrythatweight Day of Action, inspired by Columbia student Emma Sulkowicz' performance art senior thesis - "Carry That Weight." Sulkowicz has spent the last two months carrying a dorm mattress around campus, which she says she'll continue to do so until the male student whom she alleges raped her leaves Columbia, either by university action or his own volition.

Here are some pictures from the Columbia rally, which reportedly features dozens of mattresses carried by various student organizations:
