Joseph Biden actually said...

I believe that our diversity is our strength, and that we must celebrate it at every opportunity.

I believe that we have a responsibility to support our nation's workers, and to create good jobs that pay a fair wage.

We must never forget that our strength as a nation lies in our unity, in our ability to work together towards common goals.

We must never forget that America is a nation of immigrants, and that we must work together to protect their rights and dignity.
