President Barack Obama was reduced to tears when thanking his campaign staffers at his Chicago headquarters.

The talk was captured on video and posted to YouTube.

In his speech which lasted over five minutes, the president said he was really proud of everyone "because what you guys have done means that the work that I'm doing is important, and I'm really proud of that, and I'm really proud of all of you".
