Obama made pizza news again this week. The President invited 140 people over to the White House for deep dish pizza and had it brought in from a place called Pi in St. Louis. This is of course of note since deep dish is one of his hometown's claims to fame.
The incident was reported via this AP story which is hilarious because it kinda quotes Marc Malnati, owner of Chicago's famous Lou Malnati's pizzerias in Chicago. (You can also order Lou Malnati's to be delivered packed in dry ice to anywhere in the USA.)
The only other thing to be assumed is that that St. Louis pizza place is fucking delicious. A cursory glance at the restaurant's website would seem to confirm that assumption.
