From The White House’s official transcript:

This is just the beginning.  This is one of the largest plants in the world.  And when you think in terms of 20 million feet — if you build in Manhattan a million-foot building, that’s a very big building.  They don’t get much bigger.  And here you’re talking about more.  Think of it: more than 20 million feet.  And that’s probably going to be a minimal number.

So I’m thrilled to be here in the Badger State with the hardworking men and women of Foxconn working with you.  Moments ago, we broke ground on a plant that will provide jobs for much more than 13,000 Wisconsin workers.  (Applause.)  Really something.  Really something.  Thank you, fellas.
