D.C. politicians were front-and-center Thursday morning as the ribbon was cut on the new Costco store in Fort Lincoln, made possible through $17 million of city financing. They were quickly upstaged, however, by a surprise shopper: Vice President Joe Biden, who came into the Democrat-friendly chain‘s newest outlet looking for children’s books but left with a cart full of goodies that included, according to the Post’s Rachel Weiner, “among other things, flowers, children’s  books, fire logs, a 32-inch Panasonic TV and a large apple pie.”
