That photo, snapped by a Wharton student, portrays Philadelphia-area Occupiers filling Huntsman Hall to protest a planned speech by Eric Cantor. Instead of speaking to an audience that would have consisted almost entirely of protesters, Cantor scrapped the speech. The statement from his spokesman, Brad Dayspring:
The Office of the Majority Leader was informed last night by Capitol Police that the University of Pennsylvania was unable to ensure that the attendance policy previously agreed to could be met. Wharton is a educational leader in innovation and entrepreneurship, and the Majority Leader appreciated the invitation to speak with the students, faculty, alumni, and other members of the UPENN community.
Wharton students learned hours ago that the speech wouldn't happen, but the protest broke out anyway. Among the slogans: "Eric Cantor where are you? We want to talk to you."
