"I'll call him, absolutely," Kennedy said.

Similarly, Sweeney called the supporters "courageous" in a phone call to the building Friday to endorse the sit-in.

The continuing sit-in also got an unexpected boost from Reich, who was on campus Saturday for an event sponsored by the Harvard Democrats.

Addressing a crowd of more than 200 gathered to denounce the Free Trade of the Americas Agreement, Reich said he supported the students camping out in the administrative building.

"I've dedicated a lot of my life to the proposition that people need to be paid a living wage," he said. "The notion of a working poor ought to be an oxymoron in America."

Reich said the living wage is not just an economic, but also a moral issue.

"You do not want to be morally complicit in a system that does not give people enough money for their work and that I applaud you for," he gestured to the students sticking their heads out of the open Mass. Hall windows. "You are expressing the moral consciousness of this community. Do not minimize for one second that effect students can have on the public dialogue."
