(ROUGH CUT ONLY - NO REPORTER NARRATION)

A video of President Barack Obama released on Thursday (November 8) shows him wiping away tears as he thanks young members of his campaign staff and volunteers for their hard work.

His campaign released a brief video of the president's address to staff members at his Chicago headquarters on Wednesday (November 7), the day after he defeated Republican Mitt Romney for re-election.

Becoming emotional, Obama says his work in running for office has come "full circle."

"Because what you guys have done means that the work I'm doing is important. And I'm really proud of that. I'm really proud of all of you," Obama says, wiping away tears.

The workers responded with loud applause.
