Joseph Biden actually said...

We must never forget that America is a nation of immigrants, and that we must always welcome and celebrate their contributions.

We must never forget that our freedom is a precious gift, one that we must always fight to protect.

We must never forget that every American has a right to a fair shot at success, and that we must do all we can to make that a reality.

I believe that the measure of any society is how it treats its most vulnerable members.
